* Always remove an alias when we rename the target.Rafael Espindola2013-06-121-3/+1
| | | | | | Should fix the dragonegg build bots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183845 91177308-0d34-0410-b5e6-96231b3b80d8
* [PowerPC] Expose some calling convention functions in PPCISelLowering.h.Bill Schmidt2013-06-122-29/+32
| | | | | | | | | | | | | | | This is a preparatory patch for fast-isel support. The instruction selector will need to access some functions in PPCGenCallingConv.inc, which in turn requires several helper functions to be defined. These are currently defined near the only use of PCCGenCallingConv.inc, inside PPCISelLowering.cpp. This patch moves the declaration of the functions into the associated header file to provide the needed visibility. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183844 91177308-0d34-0410-b5e6-96231b3b80d8

* [MC/DWARF] Support .debug_frame / .debug_line code alignment factorsUlrich Weigand2013-06-124-31/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | I've been comparing the object file output of LLVM's integrated assembler against the external assembler on PowerPC, and one area where differences still remain are in DWARF sections. In particular, the GNU assembler generates .debug_frame and .debug_line sections using a code alignment factor of 4, since all PowerPC instructions have size 4 and must be aligned to a multiple of 4. However, current MC code hard-codes a code alignment factor of 1. This patch changes this by adding a "minimum instruction alignment" data element to MCAsmInfo and using this as code alignment factor. This requires passing a MCContext into MCDwarfLineAddr::Encode and MCDwarfLineAddr::EncodeAdvanceLoc. Note that one caller, MCDwarfLineAddr::Write, didn't actually have that information available. However, it turns out that this routine is in fact never used in the whole code base, so the patch simply removes it. If it turns out to be needed again at a later time, it could be re-added with an updated interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183834 91177308-0d34-0410-b5e6-96231b3b80d8

* [mips] Add an IR transformation pass that optimizes calls to sqrt.Akira Hatanaka2013-06-113-1/+177

* ARM FastISel fix sext/zext foldJF Bastien2013-06-111-19/+36
| | | | | | | | | | | 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 Grosser2013-06-111-30/+20
| | | | | | | | | | | | 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

* Change how globalopt handles aliases in llvm.used.Rafael Espindola2013-06-111-100/+156
| | | | | | | | | | | | | | | | | | | | | | | | 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
