* [mips] Add an IR transformation pass that optimizes calls to sqrt.Akira Hatanaka2013-06-11
| | | | | | | | | | The pass emits a call to sqrt that has attribute "read-none". This call will be converted to an ISD::FSQRT node during DAG construction, which will turn into a mips native sqrt instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183802 91177308-0d34-0410-b5e6-96231b3b80d8
* Move PathV2.h to Path.hRafael Espindola2013-06-11
| | | | | | | Most clients have already been moved from Path V1 to V2. The ones using V1 now include PathV1.h explicitly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183801 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM FastISel fix sext/zext foldJF Bastien2013-06-11
| | | | | | | | | | | Sign- and zero-extension folding was slightly incorrect because it wasn't checking that the shift on extensions was zero. Further, I recently added AND rd, rn, #255 as a form of 8-bit zero extension, and failed to add the folding code for it. This patch fixes both issues. This patch fixes both, and the test should remain the same: test/CodeGen/ARM/fast-isel-fold.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183794 91177308-0d34-0410-b5e6-96231b3b80d8
* Make host ARM CPU feature detection independent of the vendorTobias Grosser2013-06-11
| | | | | | | | | | | | For ARM on linux we use /proc/cpuinfo to detect the host CPU's features. Linux derives these values without ever looking at the vendor of the specific CPU implementation. Hence, it adds little value, if we parse the output of /proc/cpuinfo only for certain vendors. This patch enables us to derive the correct feature flags e.g. for Qualcomm CPUs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183790 91177308-0d34-0410-b5e6-96231b3b80d8
* [PECOFF] Remove COFF header from PE header for simplicity.Rui Ueyama2013-06-11
| | | | | | | | | | | | | | | | COFF header is always present both in executable and in object file. PE header is present only in executable. So the natural way to handle PE/COFF file is treating COFF is mandatory header and PE is optional. Current data structre does not allow it, because PE header includes COFF header. Removing COFF header will simplify the code to handle PE/COFF files.

* Change how globalopt handles aliases in llvm.used.Rafael Espindola2013-06-11
| | | | | | | | | | | | | | | | | | | | | | | | Instead of a custom implementation of replaceAllUsesWith, we just call replaceAllUsesWith and recreate llvm.used and llvm.compiler-used. This change is particularity interesting because it makes llvm see through what clang is doing with static used functions in extern "C" contexts. With this change, running clang -O2 in extern "C" { __attribute__((used)) static void foo() {} } produces @llvm.used = appending global [1 x i8*] [i8* bitcast (void ()* @foo to i8*)], section "llvm.metadata" define internal void @foo() #0 { entry: ret void } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183756 91177308-0d34-0410-b5e6-96231b3b80d8
