* [yaml2obj][ELF] Make symbol table top-level key.Sean Silva2013-06-222-25/+21
| | | | | | | | | Although in reality the symbol table in ELF resides in a section, the standard requires that there be no more than one SHT_SYMTAB. To enforce this constraint, it is cleaner to group all the symbols under a top-level `Symbols` key on the object file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184627 91177308-0d34-0410-b5e6-96231b3b80d8
* This was a nifty test, but remove it.Sean Silva2013-06-211-6/+0
| | | | | | | | | | | | | | 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

| | | | | | | | | 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 Blaikie2013-06-212-1/+72
| | | | | | | | | | | | 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] Allow expressing undefined symbols.Sean Silva2013-06-211-0/+4
| | | | | | | | | | Previously we unconditionally enforced that section references in symbols in the YAML had a name that was a section name present in the object, and linked the references to that section.

* [yaml2obj][ELF] Don't explicitly set `Binding` with STB_*Sean Silva2013-06-212-6/+45
| | | | | | | | | | | | | | | Instead, just have 3 sub-lists, one for each of {STB_LOCAL,STB_GLOBAL,STB_WEAK}. This allows us to be a lot more explicit w.r.t. the symbol ordering in the object file, because if we allowed explicitly setting the STB_* `Binding` key for the symbol, then we might have ended up having to shuffle STB_LOCAL symbols to the front of the list, which is likely to cause confusion and potential for error. Also, this new approach is simpler ;) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184506 91177308-0d34-0410-b5e6-96231b3b80d8

* Update the X86 disassembler to use xacquire and xrelease when appropriate.Kevin Enderby2013-06-201-1/+29
| | | | | | | | | | | | | | | | | | This is a bit tricky as the xacquire and xrelease hints use the same bytes, 0xf2 and 0xf3, as the repne and rep prefixes. Fortunately llvm has different llvm MCInst Opcode enums for rep/xrelease and repne/xacquire. So to make this work a boolean was added the InternalInstruction struct as part of the Prefix state which is set with the added logic in readPrefixes() when decoding an instruction to determine if these prefix bytes are to be disassembled as xacquire or xrelease. Then we let the matcher pick the normal prefix instructionID and we change the Opcode after that when it is set into the MCInst being created. rdar://11019859 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184490 91177308-0d34-0410-b5e6-96231b3b80d8

* [MC] Support @ variants with directional labelsUlrich Weigand2013-06-201-1/+7
| | | | | | | | | | | | | The assembler parser common code supports recognizing symbol variants using the @ modifer. On PowerPC, it should also be possible to use (some of) those modifiers with directional labels, like "1f@l". This patch adds support for accepting symbol variants on directional labels as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184437 91177308-0d34-0410-b5e6-96231b3b80d8
* [PowerPC] Optimize @ha/@l constructsUlrich Weigand2013-06-201-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for having the assembler optimize fixups to constructs like "symbol@ha" or "symbol@l" if "symbol" can be resolved at assembler time. This optimization is already present in the PPCMCExpr.cpp code for handling PPC_HA16/PPC_LO16 target expressions. However, those target expression were used only on Darwin targets. This patch changes target expression code so that they are usable also with the GNU assembler (using the @ha / @l syntax instead of the ha16() / lo16() syntax), and changes the MCInst lowering code to generate those target expressions where appropriate. It also changes the asm parser to generate HA16/LO16 target expressions when parsing assembler source that uses the @ha / @l modifiers. The effect is that now the above- mentioned optimization automatically becomes available for those situations too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184436 91177308-0d34-0410-b5e6-96231b3b80d8

Fix that bug while I'm here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184387 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: PR14763/r183329 correct the location of indirect parametersDavid Blaikie2013-06-191-0/+70
| | | | | | | | | | | | | | | | We had been papering over a problem with location info for non-trivial types passed by value by emitting their type as references (this caused the debugger to interpret the location information correctly, but broke the type of the function). r183329 corrected the type information but lead to the debugger interpreting the pointer parameter as the value - the debug info describing the location needed an extra dereference. Use a new flag in DIVariable to add the extra indirection (either by promoting an existing DW_OP_reg (parameter passed in a register) to DW_OP_breg + 0 or by adding DW_OP_deref to an existing DW_OP_breg + n (parameter passed on the stack). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184368 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-dwarfdump: Add support for dumping the .debug_loc sectionDavid Blaikie2013-06-193-0/+39
| | | | | | | | | This is a basic implementation - we still don't have any support (that I know of) for dumping DWARF expressions in a meaningful way, so the location information itself is just printed as a sequence of bytes as we do elsewhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184361 91177308-0d34-0410-b5e6-96231b3b80d8
* [MC/DWARF] Generate multiple .debug_line entries for adjacent .loc directivesUlrich Weigand2013-06-191-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | The compiler occasionally generates multiple .loc directives in a row (at the same instruction address). These need to be transformed into multple actual .debug_line table entries, since they are used to signal certain information to the debugger (e.g. if the opening brace of a function body is on the same line as the declaration). The MCAsmStreamer version of EmitDwarfLocDirective handles this correctly by emitting a .loc directive every time it is called. However, the MCObjectStream version simply defaults to recording the information and emitting only a single table entry later, e.g. when EmitInstruction is called. This patch introduces a MCAsmStreamer::EmitDwarfLocDirective version that emits a line table entry for a .loc directive that may already be pending before recording the new directive. (This is similar to how this is handled in GNU as.) With this patch (and the code alignment factor patch) applied, I'm now getting identical DWARF .debug sections for all test-suite object files on PowerPC for the internal and the external assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184357 91177308-0d34-0410-b5e6-96231b3b80d8

* LSR: Fix the parameters used to compute the scaling factor cost.Quentin Colombet2013-06-191-0/+68
| | | | | | | | | | | | | | Prior to this change, the considered addressing modes may be invalid since the maximum and minimum offsets were not taking into account. This was causing an assertion failure. The added test case exercices that behavior. <rdar://problem/14199725> Assertion failed: (CurScaleCost >= 0 && "Legal addressing mode has an illegal cost!") git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184341 91177308-0d34-0410-b5e6-96231b3b80d8
