debuginfo: Gate all LLDB debuginfo tests on a minimum LLDB version being available
2014-10-09 09:31:03 -05:00
// min-lldb-version: 310
Add make check support(arm-linux-androideabi debuginfo)
2013-11-04 00:53:01 -06:00
Consolidate codegen-related compiler flags Move them all behind a new -C switch. This migrates some -Z flags and some top-level flags behind this -C codegen option. The -C flag takes values of the form "-C name=value" where the "=value" is optional for some flags. Flags affected: * --llvm-args => -C llvm-args * --passes => -C passes * --ar => -C ar * --linker => -C linker * --link-args => -C link-args * --target-cpu => -C target-cpu * --target-feature => -C target-fature * --android-cross-path => -C android-cross-path * --save-temps => -C save-temps * --no-rpath => -C no-rpath * -Z no-prepopulate => -C no-prepopulate-passes * -Z no-vectorize-loops => -C no-vectorize-loops * -Z no-vectorize-slp => -C no-vectorize-slp * -Z soft-float => -C soft-float * -Z gen-crate-map => -C gen-crate-map * -Z prefer-dynamic => -C prefer-dynamic * -Z no-integrated-as => -C no-integrated-as As a bonus, this also promotes the -Z extra-debug-info flag to a first class -g or --debuginfo flag. * -Z debug-info => removed * -Z extra-debug-info => -g or --debuginfo Closes #9770 Closes #12000

Run debuginfo tests against rust-enabled lldb, when possible If the rust-enabled lldb was built, then use it when running the debuginfo tests. Updating the lldb submodule was necessary as this needed a way to differentiate the rust-enabled lldb, so I added a line to the --version output. This adds compiletest commands to differentiate between the rust-enabled and non-rust-enabled lldb, as is already done for gdb. A new "rust-lldb" header directive is also added, but not used in this patch; I plan to use it in #54004. This updates all the tests.

// lldb-command:continue
Fix closed over variables not available in debuginfo for Windows MSVC The issue was that the resulting debuginfo was too complex for LLVM to translate into CodeView records correctly. As a result, it simply ignored the debuginfo which meant Windows debuggers could not display any closed over variables when stepping inside a closure. This fixes that by spilling additional variables to the stack so that the resulting debuginfo is simple (just `*my_variable.dbg.spill`) and LLVM can generate the correct CV records.

debuginfo: Make sure that type names for closure and generator environments are unique in debuginfo. Before this change, closure/generator environments coming from different instantiations of the same generic function were all assigned the same name even though they were distinct types with potentially different data layout. Now we append the generic arguments of the originating function to the type name. This commit also emits '{closure_env#0}' as the name of these types in order to disambiguate them from the accompanying closure function '{closure#0}'. Previously both were assigned the same name.

remove the `float` type It is simply defined as `f64` across every platform right now. A use case hasn't been presented for a `float` type defined as the highest precision floating point type implemented in hardware on the platform. Performance-wise, using the smallest precision correct for the use case greatly saves on cache space and allows for fitting more numbers into SSE/AVX registers. If there was a use case, this could be implemented as simply a type alias or a struct thanks to `#[cfg(...)]`. Closes #6592 The mailing list thread, for reference: https://mail.mozilla.org/pipermail/rust-dev/2013-July/004632.html
