* [yaml2obj][ELF] Align section contents in the output.Sean Silva2013-06-22
| | | | | | | | | | The improperly aligned section content in the output was causing buildbot failures. This should fix them. Incidentally, this results in a simpler and more robust API for ContiguousBlobAccumulator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184621 91177308-0d34-0410-b5e6-96231b3b80d8
* Prevent LiveRangeEdit from deleting bundled instructions.Andrew Trick2013-06-22
| | | | | | | | | We have no targets on trunk that bundle before regalloc. However, we have been advertising regalloc as bundle safe for use with out-of-tree targets. We need to at least contain the parts of the code that are still unsafe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184620 91177308-0d34-0410-b5e6-96231b3b80d8

* This was a nifty test, but remove it.Sean Silva2013-06-21
| | | | | | | | | | | | | | It wouldn't really test anything that doesn't already have a more targeted test: `yaml2obj-elf-section-basic.yaml`: Already tests that section content is correctly passed though. `yaml2obj-elf-symbol-basic.yaml` (this file): Tests that the st_value and st_size attributes of `main` are set correctly. Between those two tests, disassembling the file doesn't really add anything, so just remove mention of disassembling the file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184607 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert "Put r184469 disassembler test back on X86"Sean Silva2013-06-21
| | | | | | | | | This reverts commit r184602. In an upcoming commit, I will just remove the disassembler part of the test; it was mostly just a "nifty" thing marking a milestone but it doesn't test anything that isn't tested elsewhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184606 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Don't lose unreferenced non-trivial by-value parametersDavid Blaikie2013-06-21
| | | | | | | | | | | | A FastISel optimization was causing us to emit no information for such parameters & when they go missing we end up emitting a different function type. By avoiding that shortcut we not only get types correct (very important) but also location information (handy) - even if it's only live at the start of a function & may be clobbered later.

* [yaml2obj][ELF] Don't do disassembly in this test.Sean Silva2013-06-21

* Improve the time it takes to generating dwarf for assembly source filesKevin Enderby2013-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that have been run through the 'C' pre-processor. The implementation of SrcMgr.FindLineNumber() is slow but OK if it uses its cache when called multiple times with an SMLoc that is forward of the previous call. In the case of generating dwarf for assembly source files that have been run through the 'C' pre-processor we need to calculate the logical line number based on the last parsed cpp hash file line comment. And the current code calls SrcMgr.FindLineNumber() twice to do this causing its cache not to work and results in very slow compile times: % time /Volumes/SandBox/build-llvm/Debug+Asserts/bin/llvm-mc -triple thumbv7-apple-ios -filetype=obj -o /tmp/x.o mscorlib.dll.E -g 672.542u 0.299s 11:13.15 99.9% 0+0k 0+2io 2106pf+0w So we save the info from the last parsed cpp hash file line comment to avoid making the second call to SrcMgr.FindLineNumber() most times and end up with compile times like: % time /Volumes/SandBox/build-llvm/Debug+Asserts/bin/llvm-mc -triple thumbv7-apple-ios -filetype=obj -o /tmp/x.o mscorlib.dll.E -g 3.404u 0.104s 0:03.80 92.1% 0+0k 0+3io 2105pf+0w rdar://14156934 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184592 91177308-0d34-0410-b5e6-96231b3b80d8

* [PowerPC] Support R_PPC_REL16 family of relocationsUlrich Weigand2013-06-21
| | | | | | | | | | | | | The GNU assembler supports (as extension to the ABI) use of PC-relative relocations in half16 fields, which allows writing code like: li 1, base-. This patch adds support for those relocation types in the assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184552 91177308-0d34-0410-b5e6-96231b3b80d8
* [PowerPC] Support various tls-related modifiersUlrich Weigand2013-06-21
| | | | | | | | | | | | The current code base only supports the minimum set of tls-related relocations and @modifiers that are necessary to support compiler- generated code. This patch extends this to the full set defined in the ABI (and supported by the GNU assembler) for the benefit of the assembler parser. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184551 91177308-0d34-0410-b5e6-96231b3b80d8

* [PowerPC] Support @h modifierUlrich Weigand2013-06-21
| | | | | | | | | | | | | | This adds necessary infrastructure to support the @h modifier. Note that all required relocation types were already present (and unused). This patch provides support for using @h in the assembler; it would also be possible to now use this feature in code generated by the compiler, but this is not done yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184548 91177308-0d34-0410-b5e6-96231b3b80d8
* [PowerPC] Rename some more VK_PPC_ enumsUlrich Weigand2013-06-21
| | | | | | | | | | | | | | | This renames more VK_PPC_ enums, to make them more closely reflect the @modifier string they represent. This also prepares for adding a bunch of new VK_PPC_ enums in upcoming patches. For consistency, some MO_ flags related to VK_PPC_ enums are likewise renamed.
