2014-12-01Merged from r222339*:Daniel Sanders3-21/+161
Please note that there is a significant change to the test compared to r222339. This is because this branch generates different code compared to the trunk. The code on this branch appears to be equivalent so the test has been updated accordingly. ------------------------------------------------------------------------------- Allow EmitVAArg() to promote types and use this to fix some N32/N64 vararg issues for Mips. Summary: With this patch, passing a va_list to another function and reading 10 int's from it works correctly on a big-endian target. Based on a pair of patches by David Chisnall, one of which I've reworked for the current trunk.

[mips] Mark aggregate arguments passed in registers with the inreg attribute Summary: This allows us to easily identify them in the backend which in turn allows us to handle them correctly for big-endian targets (where they must be shifted into the upper bits of the register).

[mips] Promote all integral/enumeration types to the GPR width Summary: Ensure all integral/enumeration types are appropriately annotated with signext/zeroext. In particular, i32 now has these attributes when using the N32/N64 ABI. This paves the way for accurately representing the way the N32/N64 ABI's promotes integer arguments to i64.

[mips] Correct alignment of vectors passed in varargs for the O32 ABI. Summary: Vectors are normally 16-byte aligned, however the O32 ABI enforces a maximum alignment of 8-bytes since the base of the stack is 8-byte aligned. Previously, this was enforced on the caller side, but not on the callee side. This fixes the output of OpenCL's printf when given vectors.

[mips] Mark aggregates returned in registers with the 'inreg' attribute. Summary: This allows us to easily find them in the backend after the aggregates have been lowered to other types. This is important on big-endian targets using the N32/N64 ABI's since these ABI's must shift small structures into the upper bits of the register.

------------------------------------------------------------------------ r216531 | chandlerc | 2014-08-27 01:41:41 -0700 (Wed, 27 Aug 2014) | 22 lines Significantly fix Clang's header search for Ubuntu (and possibly other modern Debian-based distributions) due to on-going multiarch madness. It appears that when the multiarch heeader search support went into the clang driver, it went in in a quite bad state. The order of includes completely failed to match the order exhibited by GCC, and in a specific case -- when the GCC triple and the multiarch triple don't match as with i686-linux-gnu and i386-linux-gnu -- we would absolutely fail to find the libstdc++ target-specific header files. I assume that folks who have been using Clang on Ubuntu 32-bit systems have been applying weird patches to hack around this. I can't imagine how else it could have worked. This was originally reported by a 64-bit operating system user who had a 32-bit crosscompiler installed. We tried to use that rather than the bi-arch support of the 64-bit compiler, but failed due to the triple differences. I've corrected all the wrong orderings in the existing tests and added a specific test for the multiarch triple strings that are different in a significant way. This should significantly improve the usability of Clang when checked out vanilla from upstream onto Ubuntu machines with an i686 GCC installation for whatever reason. ------------------------------------------------------------------------ llvm-svn: 216587

This was always the intent when we added remark support, but was never implemented in the general case, because the first -R flags didn't need it. (-Rpass= had special handling to accomodate its argument.) -Rno-foo, -Reverything, and -Rno-everything can be used to turn off a remark, or to turn on or off all remarks. Per discussion on cfe-commits, -Weverything does not affect remarks, and -Reverything does not affect warnings or errors. The only "real" -R flag we have right now is -Rmodule-build; that flag is effectively renamed from -Wmodule-build to -Rmodule-build by this change. -Wpass and -Wno-pass (and their friends) are also renamed to -Rpass and -Rno-pass by this change; it's not completely clear whether we intended to have a -Rpass (with no =pattern), but that is unchanged by this commit, other than the flag name. The default pattern is effectively one which matches no passes. In future, we may want to make the default pattern be .*, so that -Reverything works for -Rpass properly. ------------------------------------------------------------------------ llvm-svn: 215057

Correct code is generated because the back end handles the incorrect shufflevector in a consistent manner. This patch and a companion patch for LLVM correct this problem by removing the fixup from altivec.h and the corresponding fixup from the PowerPC back end. Several test cases are also modified to reflect the now-correct LLVM IR. The vec_sums and vec_vsumsws interfaces in altivec.h are also fixed, because they used vec_perm calls intended to be recognized as vsldoi instructions. These vec_perm calls are now replaced with code that more clearly shows the intent of the transformation. ------------------------------------------------------------------------ llvm-svn: 214823
