* AsmMatchers: Use unique_ptr to manage ownership of MCParsedAsmOperandDavid Blaikie2014-06-08
| | | | | | | | | | | | I saw at least a memory leak or two from inspection (on probably untested error paths) and r206991, which was the original inspiration for this change. I ran this idea by Jim Grosbach a few weeks ago & he was OK with it. Since it's a basically mechanical patch that seemed sufficient - usual post-commit review, revert, etc, as needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210427 91177308-0d34-0410-b5e6-96231b3b80d8

* Target: remove old constructors for CallLoweringInfoSaleem Abdulrasool2014-05-17
| | | | | | | | | | This is mostly a mechanical change changing all the call sites to the newer chained-function construction pattern. This removes the horrible 15-parameter constructor for the CallLoweringInfo in favour of setting properties of the call via chained functions. No functional change beyond the removal of the old constructors are intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209082 91177308-0d34-0410-b5e6-96231b3b80d8
* TableGen: fix operand counting for aliasesTim Northover2014-05-16
| | | | | | | | | | | | | | | | | | | | | TableGen has a fairly dubious heuristic to decide whether an alias should be printed: does the alias have lest operands than the real instruction. This is bad enough (particularly with no way to override it), but it should at least be calculated consistently for both strings. This patch implements that logic: first get the *correct* string for the variant, in the same way as the Matcher, without guessing; then count the number of whitespace chars. There are basically 4 changes this brings about after the previous commits; all of these appear to be good, so I have changed the tests: + ARM64: we print "neg X, Y" instead of "sub X, xzr, Y". + ARM64: we skip implicit "uxtx" and "uxtw" modifiers. + Sparc: we print "mov A, B" instead of "or %g0, A, B". + Sparc: we print "fcmpX A, B" instead of "fcmpX %fcc0, A, B" git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208969 91177308-0d34-0410-b5e6-96231b3b80d8
* Sparc: disable printing of jmp/call aliases (C++ does it)Tim Northover2014-05-16
| | | | | | | | | | These aliases are handled entirely in C++ and only having TableGen InstAliases for some of them was confusing LLVM.

* Allow sret on the second parameter as well as the firstReid Kleckner2014-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | MSVC always places the implicit sret parameter after the implicit this parameter of instance methods. We used to handle this for x86_thiscallcc by allocating the sret parameter on the stack and leaving the this pointer in ecx, but that doesn't handle alternative calling conventions like cdecl, stdcall, fastcall, or the win64 convention. Instead, change the verifier to allow sret on the second parameter. This also requires changing the Mips and X86 backends to return the argument with the sret parameter, instead of assuming that the sret parameter comes first. The Sparc backend also returns sret parameters in a register, but I wasn't able to update it to handle secondary sret parameters. It currently calls report_fatal_error if you feed it an sret in the second parameter.

| | | | | | | | | | | | system headers above the includes of generated '.inc' files that actually contain code. In a few targets this was already done pretty consistently, but it wasn't done *really* consistently anywhere. It is strictly cleaner IMO and necessary in a bunch of places where the DEBUG_TYPE is referenced from the generated code. Consistency with the necessary places trumps. Hopefully the build bots are OK with the movement of intrin.h... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206838 91177308-0d34-0410-b5e6-96231b3b80d8
* [Modules] Make Support/Debug.h modular. This requires it to not changeChandler Carruth2014-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | behavior based on other files defining DEBUG_TYPE, which means it cannot define DEBUG_TYPE at all. This is actually better IMO as it forces folks to define relevant DEBUG_TYPEs for their files. However, it requires all files that currently use DEBUG(...) to define a DEBUG_TYPE if they don't already. I've updated all such files in LLVM and will do the same for other upstream projects. This still leaves one important change in how LLVM uses the DEBUG_TYPE macro going forward: we need to only define the macro *after* header files have been #include-ed. Previously, this wasn't possible because Debug.h required the macro to be pre-defined. This commit removes that. By defining DEBUG_TYPE after the includes two things are fixed: - Header files that need to provide a DEBUG_TYPE for some inline code can do so by defining the macro before their inline code and undef-ing it afterward so the macro does not escape. - We no longer have rampant ODR violations due to including headers with different DEBUG_TYPE definitions. This may be mostly an academic violation today, but with modules these types of violations are easy to check for and potentially very relevant. Where necessary to suppor headers with DEBUG_TYPE, I have moved the definitions below the includes in this commit. I plan to move the rest of the DEBUG_TYPE macros in LLVM in subsequent commits; this one is big enough. The comments in Debug.h, which were hilariously out of date already, have been updated to reflect the recommended practice going forward. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206822 91177308-0d34-0410-b5e6-96231b3b80d8
* [MC] Require an MCContext when constructing an MCDisassembler.Lang Hames2014-04-15
| | | | | | | | | | | | | | | | | | This patch re-introduces the MCContext member that was removed from MCDisassembler in r206063, and requires that an MCContext be passed in at MCDisassembler construction time. (Previously the MCContext member had been initialized in an ad-hoc fashion after construction). The MCCContext member can be used by MCDisassembler sub-classes to construct constant or target-specific MCExprs. This patch updates disassemblers for in-tree targets, and provides the MCRegisterInfo instance that some disassemblers were using through the MCContext (previously those backends were constructing their own MCRegisterInfo instances). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206241 91177308-0d34-0410-b5e6-96231b3b80d8

* Completely rewrite ELFObjectWriter::RecordRelocation.Rafael Espindola2014-03-29
| | | | | | | | | | | | | | | | | | | I started trying to fix a small issue, but this code has seen a small fix too many. The old code was fairly convoluted. Some of the issues it had: * It failed to check if a symbol difference was in the some section when converting a relocation to pcrel. * It failed to check if the relocation was already pcrel. * The pcrel value computation was wrong in some cases (relocation-pc.s) * It was missing quiet a few cases where it should not convert symbol relocations to section relocations, leaving the backends to patch it up. * It would not propagate the fact that it had changed a relocation to pcrel, requiring a quiet nasty work around in ARM. * It was missing comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205076 91177308-0d34-0410-b5e6-96231b3b80d8

* Replace PROLOG_LABEL with a new CFI_INSTRUCTION.Rafael Espindola2014-03-07
| | | | | | | | | | | | | | | | | | | | | | | The old system was fairly convoluted: * A temporary label was created. * A single PROLOG_LABEL was created with it. * A few MCCFIInstructions were created with the same label. The semantics were that the cfi instructions were mapped to the PROLOG_LABEL via the temporary label. The output position was that of the PROLOG_LABEL. The temporary label itself was used only for doing the mapping. The new CFI_INSTRUCTION has a 1:1 mapping to MCCFIInstructions and points to one by holding an index into the CFI instructions of this function. I did consider removing MMI.getFrameInstructions completelly and having CFI_INSTRUCTION own a MCCFIInstruction, but MCCFIInstructions have non trivial constructors and destructors and are somewhat big, so the this setup is probably better. The net result is that we don't create temporary labels that are never used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203204 91177308-0d34-0410-b5e6-96231b3b80d8
