2013-04-03X86 cost model: Vector shifts are expensive in most casesArnold Schwaighofer
The default logic does not correctly identify costs of casts because they are marked as custom on x86. For some cases, where the shift amount is a scalar we would be able to generate better code. Unfortunately, when this is the case the value (the splat) will get hoisted out of the loop, thereby making it invisible to ISel. radar://13130673 radar://13537826 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178703 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-03Implement the "mips endian" for r_info.Rafael Espindola
Normally r_info is just a 32 of 64 bit number matching the endian of the rest of the file. Unfortunately, mips 64 bit little endian is special: The top 32 bits are a little endian number and the following 32 are a big endian one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178694 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-03Implements low-level object file format specific output for COFF andEric Christopher
ELF with support for: - File headers - Section headers + data - Relocations - Symbols - Unwind data (only COFF/Win64) The output format follows a few rules: - Values are almost always output one per line (as elf-dump/coff-dump already do). - Many values are translated to something readable (like enum names), with the raw value in parentheses. - Hex numbers are output in uppercase, prefixed with "0x". - Flags are sorted alphabetically. - Lists and groups are always delimited. Example output: ---------- snip ---------- Sections [ Section { Index: 1 Name: .text (5) Type: SHT_PROGBITS (0x1) Flags [ (0x6) SHF_ALLOC (0x2) SHF_EXECINSTR (0x4) ] Address: 0x0 Offset: 0x40 Size: 33 Link: 0 Info: 0 AddressAlignment: 16 EntrySize: 0 Relocations [ 0x6 R_386_32 .rodata.str1.1 0x0 0xB R_386_PC32 puts 0x0 0x12 R_386_32 .rodata.str1.1 0x0 0x17 R_386_PC32 puts 0x0 ] SectionData ( 0000: 83EC04C7 04240000 0000E8FC FFFFFFC7 |.....$..........| 0010: 04240600 0000E8FC FFFFFF31 C083C404 |.$.........1....| 0020: C3 |.| ) } ] ---------- snip ---------- Relocations and symbols can be output standalone or together with the section header as displayed in the example. This feature set supports all tests in test/MC/COFF and test/MC/ELF (and I suspect all additional tests using elf-dump), making elf-dump and coff-dump deprecated.

2013-04-03More direct types in PowerPC AltiVec intrinsics.Ulrich Weigand
This patch follows up on work done by Bill Schmidt in r178277, and replaces most of the remaining uses of VRRC in ISEL DAG patterns. The resulting .inc files are identical except for comments, so no change in code generation is expected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178656 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-03Fix PR15632: No support for ppcf128 floating-point remainder on PowerPC.Bill Schmidt
For this we need to use a libcall. Previously LLVM didn't implement libcall support for frem, so I've added it in the usual straightforward manner. A test case from the bug report is included. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178639 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-03Add 64-bit compare + branch for SPARC v9.Jakob Stoklund Olesen
The same compare instruction is used for 32-bit and 64-bit compares. It sets two different sets of flags: icc and xcc. This patch adds a conditional branch instruction using the xcc flags for 64-bit compares. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178621 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-03Use PPC reciprocal estimates with Newton iteration in fast-math modeHal Finkel
When unsafe FP math operations are enabled, we can use the fre[s] and frsqrte[s] instructions, which generate reciprocal (sqrt) estimates, together with some Newton iteration, in order to quickly generate floating-point division and sqrt results. All of these instructions are separately optional, and so each has its own feature flag (except for the Altivec instructions, which are covered under the existing Altivec flag). Doing this is not only faster than using the IEEE-compliant fdiv/fsqrt instructions, but allows these computations to be pipelined with other computations in order to hide their overall latency. I've also added a couple of missing fnmsub patterns which turned out to be missing (but are necessary for good code generation of the Newton iterations). Altivec needs a similar fix, but that will probably be more complicated because fneg is expanded for Altivec's v4f32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178617 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-03Fix the fde encoding used by mips to match gas.Rafael Espindola
This finally fixes the encoding. The patch also * Removes eh-frame.ll. It was an unnecessary .ll to .o test that was checking the wrong value. * Merge fde-reloc.s and eh-frame.s into a single test, since the only difference was the run lines. * Don't blindly test the content of the entire .eh_frame section. It makes it hard to anyone actually fixing a bug and hitting a difference in a binary blob. Instead, use a CHECK for each field and document what is being checked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178615 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-03Remove an optimization where we were changing an objc_autorelease into an ↵Michael Gottesman
objc_autoreleaseReturnValue. The semantics of ARC implies that a pointer passed into an objc_autorelease must live until some point (potentially down the stack) where an autorelease pool is popped. On the other hand, an objc_autoreleaseReturnValue just signifies that the object must live until the end of the given function at least. Thus objc_autorelease is stronger than objc_autoreleaseReturnValue in terms of the semantics of ARC* implying that performing the given strength reduction without any knowledge of how this relates to the autorelease pool pop that is further up the stack violates the semantics of ARC. *Even though objc_autoreleaseReturnValue if you know that no RV optimization will occur is more computationally expensive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178612 91177308-0d34-0410-b5e6-96231b3b80d8
