2012-07-17Revert commit r160308. We decide to move builtins selection to the backend.Simon Atanasyan
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160353 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-16MIPS: Implement __builtin_mips_shll_qb builtin function overloading.Simon Atanasyan
This function has two versions. The first one is used for a register operand. The second one is used for an immediate number. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160308 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-13Add a per target max vector alignment field (e.g., 32-byte alignment for x86 ↵Chad Rosier
due to AVX). Currently, if no aligned attribute is specified the alignment of a vector is inferred from its size. Thus, very large vectors will be over-aligned with no benefit. Target owners should set this target max. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160209 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-11The end of a block doesn't necessarily need a line table entry unlessEric Christopher
there's something going on there. Remove the unconditional line entry and only add one if we're emitting cleanups (any other statements would be handled normally). Fixes rdar://9199234 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160033 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-09Tests: check for target availability for target-specific tests.Jim Grosbach
Lots of tests are using an explicit target triple w/o first checking that the target is actually available. Add a REQUIRES clause to a bunch of them. This should hopefully unbreak bots which don't configure w/ all targets enabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159949 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159816 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-06Add -ffp-contract = { fast | on | off } command line option support.Lang Hames
This flag sets the 'fp-contract' mode, which controls the formation of fused floating point operations. Available modes are: - Fast: Form fused operations anywhere. - On: Form fused operations where allowed by FP_CONTRACT. This is the default mode. - Off: Don't form fused operations (in future this may be relaxed to forming fused operations where it can be proved that the result won't be affected). Currently clang doesn't support the FP_CONTRACT pragma, so the 'On' and 'Off' modes are equivalent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159794 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-03Make the following changes in the way Mips handles vector arguments and returnAkira Hatanaka
values: - Return integer vectors in integer registers. - Pass vector arguments in integer registers. - Set an upper bound for argument alignment. The largest alignment is 8-byte for O32 and 16-byte for N32/64. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159676 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-02Significantly simplify CGExprAgg's logic about ignored results:John McCall
if we want to ignore a result, the Dest will be null. Otherwise, we must copy into it. This means we need to ensure a slot when loading from a volatile l-value. With all that in place, fix a bug with chained assignments into __block variables of aggregate type where we were losing insight into the actual source of the value during the second assignment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159630 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-26block literal irgen: several improvements on naming blockFariborz Jahanian
literal helper functions. All helper functions (global and locals) use block_invoke as their prefix. Local literal helper names are prefixed by their enclosing mangled function names. Blocks in non-local initializers (e.g. a global variable or a C++11 field) are prefixed by their mangled variable name. The descriminator number added to end of the name starts off with blank (for first block) and _<N> (for the N+2-th block). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159206 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-23Support the tls_model attribute (PR9788)Hans Wennborg
This adds support for the tls_model attribute. This allows the user to choose a TLS model that is better than what LLVM would select by default. For example, a variable might be declared as: __thread int x __attribute__((tls_model("initial-exec"))); if it will not be used in a shared library that is dlopen'ed. This depends on LLVM r159077. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159078 91177308-0d34-0410-b5e6-96231b3b80d8
