CMake: GetTargetTriple: new module for determining the target triple. Assign to LLVM_HOSTTRIPLE so it figures in config.h. llvm-svn: 58176
2008-10-26 08:47:52 +08:00
# Returns the host triple.
# Invokes config.guess
Undo an over zealous rename. This bit of the CMake build really is dealing in the host triple, be honest about it and document the decision to default the target triple to the host triple unless overridden. llvm-svn: 148822

[cmake] Determine MSVC host triple correctly when cross-compiling CMAKE_CL_64 will never be set when cross-compiling with clang-cl, since CMake relies on an actual VS environment in order to determine it. Instead, use the size of a void pointer to determine the bit width of the host compiler (and therefore the host triple), which works for both native and cross compilation. Note that, with the impending advent of Windows on AArch64, assuming that a 64-bit host == x86_64 isn't correct either, but that's something to be addressed in a follow-up.

[AIX] Improve 32/64-bit build configuration Summary: AIX supports both 32-bit and 64-bit environments (with 32-bit being the default). This patch improves support for building LLVM on AIX in both 32-bit and 64-bit mode. - Change host detection to return correct 32/64-bit triple as config_guess does not return the correct version on 64-bit. This can confuse JIT tests and other things that care about what the host triple is. - Remove manual setting of 64-bit flags on AIX. AIX provides OBJECT_MODE environment variable to enable the user to obtain a 64-bit development environment. CMake will properly set these flags provided the user sets the correct OBJECT_MODE before configuring and setting them manually will interfere with 32-bit builds. - Don't present the LLVM_BUILD_32_BITS option on AIX, users should use OBJECT_MODE when running CMake instead.
