On Linux/Mac, I got a segmentation fault:

The variable `output` or `out_filename` becomes (null) after the definition
of `fn unlib`. Move the function defintion to the beginning seems
prevent the crash on Linux.
[crate_type = "lib"] builds it as a library.
[crate_type = "bin"] builds it as an executable.
Executable is the default. --lib and --bin switches override.
See src/test/run-pass/nested-patterns.rs for some examples. The syntax is
boundvar@subpattern
Which will match the subpattern as usual, but also bind boundvar to the
whole matched value.
Closes#838
Also shuffles around the organization of numeric literals and types,
separating by int/uint/float instead of machine-vs-non-machine types.
This simplifies some code.
Closes#974Closes#1252
When unwinding through __morestack the stack limit in the TLS is invalidated
and must be reset. Instead of actually landing at __morestack we're
just going to make all our Rust landing pads call upcall_reset_stack_limit,
which will find the stack segment that corresponds to the current stack
pointer and put the limit in the TLS.
Also massively expand the stack segment red zone to make more room for the
dynamic linker. Will fix in the future.
LLVM code generator emits the ".file filename" directive for ELF
backends. Value of the "filename" is set as the LLVM module identifier.
Due to a LLVM MC bug[1], LLVM crashes if the module identifer is same as
other symbols such as a function name in the module.
This patch adds a ".rc" suffix (means crates) to LLVM module identifier
to workaround the bug.
Fixes issue #1251.
