[llvm-commits] [PATCH] Fix for bug 11060: configure --target does not work

[Sebastian Pop]

Hi,

the attached patches make the configure option --target usable to build
a compiler that will target by default the architecture specified by this flag.
Without these patches, clang builds a toolchain that targets the host
unless the option -ccc-host-triple is used (I think this flag should be called
-ccc-target-triple and renamed in a different patch.)

The first patch 0001-add-getDefaultTargetTriple.patch defines
LLVM_DEFAULT_TARGET_TRIPLE based on the value of $target set by
the configure script.  This is then used in llvm::sys::getDefaultTargetTriple
to return the triple corresponding to the target architecture.

The second patch 0001-use-getDefaultTargetTriple-instead-of-getHostTriple.patch
is against clang, and it replaces all the uses of llvm::sys::getHostTriple
with llvm::sys::getDefaultTargetTriple.

The patches have been tested on amd64-linux with no extra configure flags,
and with specifying the --target flag to build cross compilers to arm and other
architectures.  Ok to apply?

Thanks,
Sebastian Pop
