------------------------------------------------------------------------ r215046 | rsmith | 2014-08-06 17:24:21 -0700 (Wed, 06 Aug 2014) | 19 lines Use -Rblah, not -Wblah, to control remark diagnostics. 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

------------------------------------------------------------------------ r214801 | wschmidt | 2014-08-04 18:21:26 -0500 (Mon, 04 Aug 2014) | 19 lines [PPC64LE] Fix wrong IR for vec_sld and vec_vsldoi My original LE implementation of the vsldoi instruction, with its altivec.h interfaces vec_sld and vec_vsldoi, produces incorrect shufflevector operations in the LLVM IR. 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

2014-07-22Sema: correct handling for __va_start for WoASaleem Abdulrasool4-1/+131
Windows ARM indicates __va_start as a variadic function. However, the function itself is treated as having 4 formal arguments: - (out) pointer to the va_list - (in) address of the last named argument - (in) slot size for the type of the last argument - address of the last named argument The last argument does not seem to have any bearing on codegen, and thus is not explicitly type checked at this point. Unlike the previous handling for __va_start, it does not currently validate if the parameter is the last named parameter (it seems that MSVC currently accepts this). llvm-svn: 213595
2014-07-22Avoid crash if default argument parsed with errors.Serge Pavlov5-5/+12
If function parameters have default values, and that of the second parameter is parsed with errors, function declaration would have a parameter without default value that follows a parameter with that. Such declaration breaks logic of selecting overloaded function. As a solution, put opaque object as default value in such case. This patch fixes PR20055.

2014-07-22-fms-extensions: Implement half of #pragma init_segReid Kleckner14-25/+232
Summary: This pragma is very rare. We could *hypothetically* lower some uses of it down to @llvm.global_ctors, but given that GlobalOpt isn't able to optimize prioritized global ctors today, there's really no point. If we wanted to do this in the future, I would check if the section used in the pragma started with ".CRT$XC" and had up to two characters after it. Those two characters could form the 16-bit initialization priority that we support in @llvm.global_ctors. We would have to teach LLVM to lower prioritized global ctors on COFF as well. This should let us compile some silly uses of this pragma in WebKit / Blink. Reviewers: rsmith, majnemer Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D4549 llvm-svn: 213593

2014-07-21clang-format vs plugin: set version number from cmake (PR20307)Hans Wennborg2-4/+11
Previously it was hard-coded to 1.0, which meant the installer would not install the plugin over previous versions. This commit makes us use LLVM's major.minor.patch version from cmake, or whatever CLANG_FORMAT_VS_VERSION is set to when configuring the build. It's pretty dirty to update a configuration file in the source directory from the cmake build like this. However, the plugin build is already dirty in this regard since it builds in the source dir when visual studio, and then copies out the resulting vsix. llvm-svn: 213584

2014-07-21[PowerPC] Optimize passing certain aggregates by valueUlrich Weigand4-13/+57
In addition to enabling ELFv2 homogeneous aggregate handling, LLVM support to pass array types directly also enables a performance enhancement. We can now pass (non-homogeneous) aggregates that fit fully in registers as direct integer arrays, using an element type to encode the alignment requirement (that would otherwise go to the "byval align" field). This is preferable since "byval" forces the back-end to write the aggregate out to the stack, even if it could be passed fully in registers. This is particularly annoying on ELFv2, if there is no parameter save area available, since we then need to allocate space on the callee's stack just to hold those aggregates. Note that to implement this optimization, this patch does not attempt to fully anticipate register allocation rules as (defined in the ABI and) implemented in the back-end. Instead, the patch is simply passing *any* aggregate passed by value using the array mechanism if its size is up to 64 bytes. This means that some of those will end up being passed in stack slots anyway, but the generated code shouldn't be any worse either. (*Large* aggregates remain passed using "byval" to enable optimized copying via memcpy etc.) llvm-svn: 213495
2014-07-21[PowerPC] Support the ELFv2 ABIUlrich Weigand2-9/+591
This patch implements clang support for the PowerPC ELFv2 ABI. Together with a series of companion patches in LLVM, this makes clang/LLVM fully usable on powerpc64le-linux. Most of the ELFv2 ABI changes are fully implemented on the LLVM side. On the clang side, we only need to implement some changes in how aggregate types are passed by value. Specifically, we need to: - pass (and return) "homogeneous" floating-point or vector aggregates in FPRs and VRs (this is similar to the ARM homogeneous aggregate ABI) - return aggregates of up to 16 bytes in one or two GPRs The second piece is trivial to implement in any case. To implement the first piece, this patch makes use of infrastructure recently enabled in the LLVM PowerPC back-end to support passing array types directly, where the array element type encodes properties needed to handle homogeneous aggregates correctly. Specifically, the array element type encodes: - whether the parameter should be passed in FPRs, VRs, or just GPRs/stack slots (for float / vector / integer element types, respectively) - what the alignment requirements of the parameter are when passed in GPRs/stack slots (8 for float / 16 for vector / the element type size for integer element types) -- this corresponds to the "byval align" field With this support in place, the clang part simply needs to *detect* whether an aggregate type implements a float / vector homogeneous aggregate as defined by the ELFv2 ABI, and if so, pass/return it as array type using the appropriate float / vector element type. llvm-svn: 213494
