* [yaml2obj] Initial ELF support.Sean Silva2013-06-10
| | | | | | | | | Currently, only emitting the ELF header is supported (no sections or segments). The ELFYAML code organization is broadly similar to the COFFYAML code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183711 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: diagnose ARM/Thumb assembly switches on CPUs only supporting one.Tim Northover2013-06-10
| | | | | | | | | | | Some ARM CPUs only support ARM mode (ancient v4 ones, for example) and some only support Thumb mode (M-class ones currently). This makes sure such CPUs default to the correct mode and makes the AsmParser diagnose an attempt to switch modes incorrectly. rdar://14024354 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183710 91177308-0d34-0410-b5e6-96231b3b80d8

* X86: Stop LEA64_32r doing unspeakable things to its arguments.Tim Northover2013-06-10
| | | | | | | | | | | | Previously LEA64_32r went through virtually the entire backend thinking it was using 32-bit registers until its blissful illusions were cruelly snatched away by MCInstLower and 64-bit equivalents were substituted at the last minute. This patch makes it behave normally, and take 64-bit registers as sources all the way through. Previous uses (for 32-bit arithmetic) are accommodated via SUBREG_TO_REG instructions which make the types and classes agree properly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183693 91177308-0d34-0410-b5e6-96231b3b80d8

* [PowerPC] Support extended sc mnemonicUlrich Weigand2013-06-10
| | | | | | | | | | | A plain "sc" without argument is supposed to be treated like "sc 0" by the assembler. This patch adds a corresponding alias. Problem reported by Joerg Sonnenberger. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183687 91177308-0d34-0410-b5e6-96231b3b80d8
* [PowerPC] Support branch mnemonics with implied CR0Ulrich Weigand2013-06-10
| | | | | | | | | | | | The extended branch mnemonics are supposed to use an implied CR0 if there is no explicit condition register specified. This patch adds extra variants of the mnemonics to this effect. Problem reported by Joerg Sonnenberger. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183686 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix ARM unwind opcode assembler in several cases.Logan Chien2013-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes to ARM unwind opcode assembler: * Fix multiple .save or .vsave directives. Besides, the order is preserved now. * For the directives which will generate multiple opcodes, such as ".save {r0-r11}", the order of the unwind opcode is fixed now, i.e. the registers with less encoding value are popped first. * Fix the $sp offset calculation. Now, we can use the .setfp, .pad, .save, and .vsave directives at any order. Changes to test cases: * Add test cases to check the order of multiple opcodes for the .save directive. * Fix the incorrect $sp offset in the test case. The stack pointer offset specified in the test case was incorrect. (Changed test cases: ehabi-mc-section.ll and ehabi-mc.ll) * The opcode to restore $sp are slightly reordered. The behavior are not changed, and the new output is same as the output of GNU as. (Changed test cases: eh-directive-pad.s and eh-directive-setfp.s) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183627 91177308-0d34-0410-b5e6-96231b3b80d8

* R600: Use a refined heuristic to choose when switching clauseVincent Lejeune2013-06-07
| | | | | | | | | | | | | | | This is using a hint from AMD APP OpenCL Programming Guide with empirically tweaked parameters. I used Unigine Heaven 3.0 to determine best parameters on my system (i7 2600/Radeon 6950/Kernel 3.9.4) the benchmark : it went from 38.8 average fps to 39.6, which is ~3% gain. (Lightmark 2008.2 gain is much more marginal: from 537 to 539) There is no lit test provided as the parameter were determined empirically and it it would be nearly impossiblet to find a test program that check for optimal behavior. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183593 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix an assertion in MemCpyOpt pass.Shuxin Yang2013-06-07
| | | | | | | | | | | | | | | | | | | | | | The MemCpyOpt pass is capable of optimizing: callee(&S); copy N bytes from S to D. into: callee(&D); subject to some legality constraints. Assertion is triggered when the compiler tries to evalute "sizeof(typeof(D))", while D is an opaque-typed, 'sret' formal argument of function being compiled. i.e. the signature of the func being compiled is something like this: T caller(...,%opaque* noalias nocapture sret %D, ...) The fix is that when come across such situation, instead of calling some utility functions to get the size of D's type (which will crash), we simply assume D has at least N bytes as implified by the copy-instruction. rdar://14073661 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183584 91177308-0d34-0410-b5e6-96231b3b80d8
