Make configure respect (and save) values for `CC`, `CXX`, `CFLAGS`, etc. I mostly tried to remain backwards compatible with old invocations of the `configure` script; if you do not want to use `CC` et al., you should not have to; you can keep using `--enable-clang` and/or `--enable-ccache`. The overall intention is to capture the following precedences for guessing the C compiler: 1. Value of `CC` at make invocation time. 2. Value of `CC` at configure invocation time. 3. Compiler inferred at configure invocation time (`gcc` or `clang`). The strategy is to check (at `configure` time) if each of the environment variables is set, and if so, save its value in a corresponding `CFG_` variable (e.g. `CFG_CC`). Then, in the makefiles, if `CC` is not set but `CFG_CC` is, then we use the `CFG_CC` setting as `CC`. Also, I fold the potential user-provided `CFLAGS` and `CXXFLAGS` values into all of the per-platform `CFLAGS` and `CXXFLAGS` settings. (This was opposed to adding `$(CFLAGS)` in an ad-hoc manner to various parts of the mk files.) Fix #13805. ---- Note that if you try to set the compiler to clang via the `CC` and `CXX` environment variables, you will probably need to also set `CXXFLAGS` to `--enable-libcpp` so that LLVM will be configured properly. ---- Introduce CFG_USING_CLANG, which is distinguished from CFG_ENABLE_CLANG because the former represents "we think we're using clang, choose appropriate warning-control options" while the latter represents "we asked configure (or the host required) that we attempt to use clang, so check that we have an appropriate version of clang." The main reason I added this is that I wanted to allow the user to choose clang via setting the `CC` environment variable, but I did not want that method of selection to get confused with the user passing the `--enable-clang` option. ---- A digression: The `configure` script does not infer the compiler setting if `CC` is set; but if `--enable-clang` was passed, then it *does* still attempt to validate that the clang version is compatible. Supporting this required revising `CLANG_VERSION` check to be robust in face of user-provided `CC` value. In particular, on Travis, the `CC` is set to `gcc` and so the natural thing to do is to attempt to use `gcc` as the compiler, but Travis is also passing `--enable-clang` to configure. So, what is the right answer in the face of these contradictory requests? One approach would be to have `--enable-clang` supersede the setting for `CC` (and instead just call whatever we inferred for `CFG_CLANG`). That sounds maximally inflexible to me (pnkfelix): a developer requesting a `CC` value probably wants it respected, and should be able to set it to something else; it is harder for that developer to hack our configure script to change its inferred path to clang. A second approach would be to blindly use the `CC` value but keep going through the clang version check when `--enable-clang` is turned on. But on Travis (a Linux host), the `gcc` invocation won't print a clang version, so we would not get past the CLANG_VERSION check in that context. A third approach would be to never run the CLANG_VERSION check if `CC` is explicitly set. That is not a terrible idea; but if the user uses `CC` to pass in a path to some other version of clang that they want to test, probably should still send that through the `CLANG_VERSION` check. So in the end I (pnkfelix) took a fourth approach: do the CLANG_VERSION check if `CC` is unset *or* if `CC` is set to a string ending with `clang`. This way setting `CC` to things like `path/to/clang` or `ccache clang` will still go through the CLANG_VERSION check, while setting `CC` to `gcc` or some unknown compiler will skip the CLANG_VERSION check (regardless of whether the user passed --enable-clang to `configure`). ---- Drive-by fixes: * The call that sets `CFG_CLANG_VERSION` was quoting `"$CFG_CC"` in its invocation, but that does not play nicely with someone who sets `$CFG_CC` to e.g. `ccache clang`, since you do not want to intepret that whole string as a command. (On the other hand, a path with spaces might need the quoted invocation. Not sure which one of these corner use-cases is more important to support.) * Fix chk_cc error message to point user at `gcc` not `cc`.

Add generation of static libraries to rustc This commit implements the support necessary for generating both intermediate and result static rust libraries. This is an implementation of my thoughts in https://mail.mozilla.org/pipermail/rust-dev/2013-November/006686.html. When compiling a library, we still retain the "lib" option, although now there are "rlib", "staticlib", and "dylib" as options for crate_type (and these are stackable). The idea of "lib" is to generate the "compiler default" instead of having too choose (although all are interchangeable). For now I have left the "complier default" to be a dynamic library for size reasons. Of the rust libraries, lib{std,extra,rustuv} will bootstrap with an rlib/dylib pair, but lib{rustc,syntax,rustdoc,rustpkg} will only be built as a dynamic object. I chose this for size reasons, but also because you're probably not going to be embedding the rustc compiler anywhere any time soon. Other than the options outlined above, there are a few defaults/preferences that are now opinionated in the compiler: * If both a .dylib and .rlib are found for a rust library, the compiler will prefer the .rlib variant. This is overridable via the -Z prefer-dynamic option * If generating a "lib", the compiler will generate a dynamic library. This is overridable by explicitly saying what flavor you'd like (rlib, staticlib, dylib). * If no options are passed to the command line, and no crate_type is found in the destination crate, then an executable is generated With this change, you can successfully build a rust program with 0 dynamic dependencies on rust libraries. There is still a dynamic dependency on librustrt, but I plan on removing that in a subsequent commit. This change includes no tests just yet. Our current testing infrastructure/harnesses aren't very amenable to doing flavorful things with linking, so I'm planning on adding a new mode of testing which I believe belongs as a separate commit.

Fixes for compilation to iOS: - remove /usr/include from the include path since the iOS SDK provides the correct version - `_NSGetEnviron()` is private and not available on iOS - `.align` without an argument is not allowed with the Apple tools. 2^2 should be the default alignment - ignore error messages for XCode < 5 - pass include path to libuv

Make configure respect (and save) values for `CC`, `CXX`, `CFLAGS`, etc. I mostly tried to remain backwards compatible with old invocations of the `configure` script; if you do not want to use `CC` et al., you should not have to; you can keep using `--enable-clang` and/or `--enable-ccache`. The overall intention is to capture the following precedences for guessing the C compiler: 1. Value of `CC` at make invocation time. 2. Value of `CC` at configure invocation time. 3. Compiler inferred at configure invocation time (`gcc` or `clang`). The strategy is to check (at `configure` time) if each of the environment variables is set, and if so, save its value in a corresponding `CFG_` variable (e.g. `CFG_CC`). Then, in the makefiles, if `CC` is not set but `CFG_CC` is, then we use the `CFG_CC` setting as `CC`. Also, I fold the potential user-provided `CFLAGS` and `CXXFLAGS` values into all of the per-platform `CFLAGS` and `CXXFLAGS` settings. (This was opposed to adding `$(CFLAGS)` in an ad-hoc manner to various parts of the mk files.) Fix #13805. ---- Note that if you try to set the compiler to clang via the `CC` and `CXX` environment variables, you will probably need to also set `CXXFLAGS` to `--enable-libcpp` so that LLVM will be configured properly. ---- Introduce CFG_USING_CLANG, which is distinguished from CFG_ENABLE_CLANG because the former represents "we think we're using clang, choose appropriate warning-control options" while the latter represents "we asked configure (or the host required) that we attempt to use clang, so check that we have an appropriate version of clang." The main reason I added this is that I wanted to allow the user to choose clang via setting the `CC` environment variable, but I did not want that method of selection to get confused with the user passing the `--enable-clang` option. ---- A digression: The `configure` script does not infer the compiler setting if `CC` is set; but if `--enable-clang` was passed, then it *does* still attempt to validate that the clang version is compatible. Supporting this required revising `CLANG_VERSION` check to be robust in face of user-provided `CC` value. In particular, on Travis, the `CC` is set to `gcc` and so the natural thing to do is to attempt to use `gcc` as the compiler, but Travis is also passing `--enable-clang` to configure. So, what is the right answer in the face of these contradictory requests? One approach would be to have `--enable-clang` supersede the setting for `CC` (and instead just call whatever we inferred for `CFG_CLANG`). That sounds maximally inflexible to me (pnkfelix): a developer requesting a `CC` value probably wants it respected, and should be able to set it to something else; it is harder for that developer to hack our configure script to change its inferred path to clang. A second approach would be to blindly use the `CC` value but keep going through the clang version check when `--enable-clang` is turned on. But on Travis (a Linux host), the `gcc` invocation won't print a clang version, so we would not get past the CLANG_VERSION check in that context. A third approach would be to never run the CLANG_VERSION check if `CC` is explicitly set. That is not a terrible idea; but if the user uses `CC` to pass in a path to some other version of clang that they want to test, probably should still send that through the `CLANG_VERSION` check. So in the end I (pnkfelix) took a fourth approach: do the CLANG_VERSION check if `CC` is unset *or* if `CC` is set to a string ending with `clang`. This way setting `CC` to things like `path/to/clang` or `ccache clang` will still go through the CLANG_VERSION check, while setting `CC` to `gcc` or some unknown compiler will skip the CLANG_VERSION check (regardless of whether the user passed --enable-clang to `configure`). ---- Drive-by fixes: * The call that sets `CFG_CLANG_VERSION` was quoting `"$CFG_CC"` in its invocation, but that does not play nicely with someone who sets `$CFG_CC` to e.g. `ccache clang`, since you do not want to intepret that whole string as a command. (On the other hand, a path with spaces might need the quoted invocation. Not sure which one of these corner use-cases is more important to support.) * Fix chk_cc error message to point user at `gcc` not `cc`.

Fix unwinding on OS X 10.9. OS X 10.9's linker has a bug that results in it failing to preserve DWARF unwind information when passed the -no_compact_unwind flag. This flag is passed on OS X because the unwind information for __morestack cannot be represented by the compact unwind format. We can work around this problem by using a more targeted approach to disabling compact unwind information. The OS X linker looks for a particular pattern in the DWARF unwind information and will not attempt to convert the unwind information to the compact format. The pattern in question is the return address register being saved twice to the same location. Fixes #6849.

Make configure respect (and save) values for `CC`, `CXX`, `CFLAGS`, etc. I mostly tried to remain backwards compatible with old invocations of the `configure` script; if you do not want to use `CC` et al., you should not have to; you can keep using `--enable-clang` and/or `--enable-ccache`. The overall intention is to capture the following precedences for guessing the C compiler: 1. Value of `CC` at make invocation time. 2. Value of `CC` at configure invocation time. 3. Compiler inferred at configure invocation time (`gcc` or `clang`). The strategy is to check (at `configure` time) if each of the environment variables is set, and if so, save its value in a corresponding `CFG_` variable (e.g. `CFG_CC`). Then, in the makefiles, if `CC` is not set but `CFG_CC` is, then we use the `CFG_CC` setting as `CC`. Also, I fold the potential user-provided `CFLAGS` and `CXXFLAGS` values into all of the per-platform `CFLAGS` and `CXXFLAGS` settings. (This was opposed to adding `$(CFLAGS)` in an ad-hoc manner to various parts of the mk files.) Fix #13805. ---- Note that if you try to set the compiler to clang via the `CC` and `CXX` environment variables, you will probably need to also set `CXXFLAGS` to `--enable-libcpp` so that LLVM will be configured properly. ---- Introduce CFG_USING_CLANG, which is distinguished from CFG_ENABLE_CLANG because the former represents "we think we're using clang, choose appropriate warning-control options" while the latter represents "we asked configure (or the host required) that we attempt to use clang, so check that we have an appropriate version of clang." The main reason I added this is that I wanted to allow the user to choose clang via setting the `CC` environment variable, but I did not want that method of selection to get confused with the user passing the `--enable-clang` option. ---- A digression: The `configure` script does not infer the compiler setting if `CC` is set; but if `--enable-clang` was passed, then it *does* still attempt to validate that the clang version is compatible. Supporting this required revising `CLANG_VERSION` check to be robust in face of user-provided `CC` value. In particular, on Travis, the `CC` is set to `gcc` and so the natural thing to do is to attempt to use `gcc` as the compiler, but Travis is also passing `--enable-clang` to configure. So, what is the right answer in the face of these contradictory requests? One approach would be to have `--enable-clang` supersede the setting for `CC` (and instead just call whatever we inferred for `CFG_CLANG`). That sounds maximally inflexible to me (pnkfelix): a developer requesting a `CC` value probably wants it respected, and should be able to set it to something else; it is harder for that developer to hack our configure script to change its inferred path to clang. A second approach would be to blindly use the `CC` value but keep going through the clang version check when `--enable-clang` is turned on. But on Travis (a Linux host), the `gcc` invocation won't print a clang version, so we would not get past the CLANG_VERSION check in that context. A third approach would be to never run the CLANG_VERSION check if `CC` is explicitly set. That is not a terrible idea; but if the user uses `CC` to pass in a path to some other version of clang that they want to test, probably should still send that through the `CLANG_VERSION` check. So in the end I (pnkfelix) took a fourth approach: do the CLANG_VERSION check if `CC` is unset *or* if `CC` is set to a string ending with `clang`. This way setting `CC` to things like `path/to/clang` or `ccache clang` will still go through the CLANG_VERSION check, while setting `CC` to `gcc` or some unknown compiler will skip the CLANG_VERSION check (regardless of whether the user passed --enable-clang to `configure`). ---- Drive-by fixes: * The call that sets `CFG_CLANG_VERSION` was quoting `"$CFG_CC"` in its invocation, but that does not play nicely with someone who sets `$CFG_CC` to e.g. `ccache clang`, since you do not want to intepret that whole string as a command. (On the other hand, a path with spaces might need the quoted invocation. Not sure which one of these corner use-cases is more important to support.) * Fix chk_cc error message to point user at `gcc` not `cc`.

Get rid of the android-cross-path flag to rustc. There's no need to include this specific flag just for android. We can already deal with what it tries to solve by using -C linker=/path/to/cc and -C ar=/path/to/ar. The Makefiles for rustc already set this up when we're crosscompiling. I did add the flag to compiletest though so it can find gdb. Though, I'm pretty sure we don't run debuginfo tests on android anyways right now. [breaking-change]

This way setting `CC` to things like `path/to/clang` or `ccache clang` will still go through the CLANG_VERSION check, while setting `CC` to `gcc` or some unknown compiler will skip the CLANG_VERSION check (regardless of whether the user passed --enable-clang to `configure`). ---- Drive-by fixes: * The call that sets `CFG_CLANG_VERSION` was quoting `"$CFG_CC"` in its invocation, but that does not play nicely with someone who sets `$CFG_CC` to e.g. `ccache clang`, since you do not want to intepret that whole string as a command. (On the other hand, a path with spaces might need the quoted invocation. Not sure which one of these corner use-cases is more important to support.) * Fix chk_cc error message to point user at `gcc` not `cc`.

Make configure respect (and save) values for `CC`, `CXX`, `CFLAGS`, etc. I mostly tried to remain backwards compatible with old invocations of the `configure` script; if you do not want to use `CC` et al., you should not have to; you can keep using `--enable-clang` and/or `--enable-ccache`. The overall intention is to capture the following precedences for guessing the C compiler: 1. Value of `CC` at make invocation time. 2. Value of `CC` at configure invocation time. 3. Compiler inferred at configure invocation time (`gcc` or `clang`). The strategy is to check (at `configure` time) if each of the environment variables is set, and if so, save its value in a corresponding `CFG_` variable (e.g. `CFG_CC`). Then, in the makefiles, if `CC` is not set but `CFG_CC` is, then we use the `CFG_CC` setting as `CC`. Also, I fold the potential user-provided `CFLAGS` and `CXXFLAGS` values into all of the per-platform `CFLAGS` and `CXXFLAGS` settings. (This was opposed to adding `$(CFLAGS)` in an ad-hoc manner to various parts of the mk files.) Fix #13805. ---- Note that if you try to set the compiler to clang via the `CC` and `CXX` environment variables, you will probably need to also set `CXXFLAGS` to `--enable-libcpp` so that LLVM will be configured properly. ---- Introduce CFG_USING_CLANG, which is distinguished from CFG_ENABLE_CLANG because the former represents "we think we're using clang, choose appropriate warning-control options" while the latter represents "we asked configure (or the host required) that we attempt to use clang, so check that we have an appropriate version of clang." The main reason I added this is that I wanted to allow the user to choose clang via setting the `CC` environment variable, but I did not want that method of selection to get confused with the user passing the `--enable-clang` option. ---- A digression: The `configure` script does not infer the compiler setting if `CC` is set; but if `--enable-clang` was passed, then it *does* still attempt to validate that the clang version is compatible. Supporting this required revising `CLANG_VERSION` check to be robust in face of user-provided `CC` value. In particular, on Travis, the `CC` is set to `gcc` and so the natural thing to do is to attempt to use `gcc` as the compiler, but Travis is also passing `--enable-clang` to configure. So, what is the right answer in the face of these contradictory requests? One approach would be to have `--enable-clang` supersede the setting for `CC` (and instead just call whatever we inferred for `CFG_CLANG`). That sounds maximally inflexible to me (pnkfelix): a developer requesting a `CC` value probably wants it respected, and should be able to set it to something else; it is harder for that developer to hack our configure script to change its inferred path to clang. A second approach would be to blindly use the `CC` value but keep going through the clang version check when `--enable-clang` is turned on. But on Travis (a Linux host), the `gcc` invocation won't print a clang version, so we would not get past the CLANG_VERSION check in that context. A third approach would be to never run the CLANG_VERSION check if `CC` is explicitly set.

The purpose of these headers is to fix issues with mingw v4.0, as described in #9246. This works by adding this directory to GCC include search path before mingw system headers directories, so we can intercept their inclusions and add missing definitions without having to modify files in mingw/include.

Make configure respect (and save) values for `CC`, `CXX`, `CFLAGS`, etc. I mostly tried to remain backwards compatible with old invocations of the `configure` script; if you do not want to use `CC` et al., you should not have to; you can keep using `--enable-clang` and/or `--enable-ccache`. The overall intention is to capture the following precedences for guessing the C compiler: 1. Value of `CC` at make invocation time. 2. Value of `CC` at configure invocation time. 3. Compiler inferred at configure invocation time (`gcc` or `clang`). The strategy is to check (at `configure` time) if each of the environment variables is set, and if so, save its value in a corresponding `CFG_` variable (e.g. `CFG_CC`). Then, in the makefiles, if `CC` is not set but `CFG_CC` is, then we use the `CFG_CC` setting as `CC`. Also, I fold the potential user-provided `CFLAGS` and `CXXFLAGS` values into all of the per-platform `CFLAGS` and `CXXFLAGS` settings. (This was opposed to adding `$(CFLAGS)` in an ad-hoc manner to various parts of the mk files.) Fix #13805. ---- Note that if you try to set the compiler to clang via the `CC` and `CXX` environment variables, you will probably need to also set `CXXFLAGS` to `--enable-libcpp` so that LLVM will be configured properly. ---- Introduce CFG_USING_CLANG, which is distinguished from CFG_ENABLE_CLANG because the former represents "we think we're using clang, choose appropriate warning-control options" while the latter represents "we asked configure (or the host required) that we attempt to use clang, so check that we have an appropriate version of clang." The main reason I added this is that I wanted to allow the user to choose clang via setting the `CC` environment variable, but I did not want that method of selection to get confused with the user passing the `--enable-clang` option. ---- A digression: The `configure` script does not infer the compiler setting if `CC` is set; but if `--enable-clang` was passed, then it *does* still attempt to validate that the clang version is compatible. Supporting this required revising `CLANG_VERSION` check to be robust in face of user-provided `CC` value. In particular, on Travis, the `CC` is set to `gcc` and so the natural thing to do is to attempt to use `gcc` as the compiler, but Travis is also passing `--enable-clang` to configure. So, what is the right answer in the face of these contradictory requests? One approach would be to have `--enable-clang` supersede the setting for `CC` (and instead just call whatever we inferred for `CFG_CLANG`). That sounds maximally inflexible to me (pnkfelix): a developer requesting a `CC` value probably wants it respected, and should be able to set it to something else; it is harder for that developer to hack our configure script to change its inferred path to clang. A second approach would be to blindly use the `CC` value but keep going through the clang version check when `--enable-clang` is turned on. But on Travis (a Linux host), the `gcc` invocation won't print a clang version, so we would not get past the CLANG_VERSION check in that context. A third approach would be to never run the CLANG_VERSION check if `CC` is explicitly set. That is not a terrible idea; but if the user uses `CC` to pass in a path to some other version of clang that they want to test, probably should still send that through the `CLANG_VERSION` check. So in the end I (pnkfelix) took a fourth approach: do the CLANG_VERSION check if `CC` is unset *or* if `CC` is set to a string ending with `clang`. This way setting `CC` to things like `path/to/clang` or `ccache clang` will still go through the CLANG_VERSION check, while setting `CC` to `gcc` or some unknown compiler will skip the CLANG_VERSION check (regardless of whether the user passed --enable-clang to `configure`). ---- Drive-by fixes: * The call that sets `CFG_CLANG_VERSION` was quoting `"$CFG_CC"` in its invocation, but that does not play nicely with someone who sets `$CFG_CC` to e.g. `ccache clang`, since you do not want to intepret that whole string as a command. (On the other hand, a path with spaces might need the quoted invocation. Not sure which one of these corner use-cases is more important to support.) * Fix chk_cc error message to point user at `gcc` not `cc`.
