* Tweak the ThinLTO pass pipelineMehdi Amini2016-05-061-17/+7
| | | | | | | | | | | | | | | | | | | | | Summary: The original ThinLTO pipeline was derived from some work I did tuning FullLTO on the test suite and SPEC. This patch reduces the amount of work done in the "linker phase" of the build, and extend the function simplifications passes performed during the "compile phase". This helps the build time by reducing the IR as much as possible during the compile phase and limiting the work to be performed during the "link phase", while keeping the performance "on par" with the existing pipeline.

* [AMDGPU][llvm-mc] Add support for sendmsg(...) syntax.Artem Tamazov2016-05-0610-36/+559
| | | | | | | | | | | | | | | | | | | Added support for sendmsg(MSG[, OP[, STREAM_ID]]) syntax in s_sendmsg and s_sendmsghalt instructions. The syntax matches the SP3 assembler/disassembler rules. That is why implicit inputs (like M0 and EXEC) are not printed to disassembly output anymore. sendmsg(...) allows only known message types and attributes, even if literals are used instead of symbolic names. However, raw literal (without "sendmsg") still can be used, and that allows for any 16-bit value. Tests updated/added. Differential Revision: http://reviews.llvm.org/D19596 llvm-svn: 268762

* [AArch64] Combine callee-save and local stack SP adjustment instructions.Geoff Berry2016-05-0617-167/+289
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: If a function needs to allocate both callee-save stack memory and local stack memory, we currently decrement/increment the SP in two steps: first for the callee-save area, and then for the local stack area. This changes the code to allocate them both at once at the very beginning/end of the function. This has two benefits: 1) there is one fewer sub/add micro-op in the prologue/epilogue 2) the stack adjustment instructions act as a scheduling barrier, so moving them to the very beginning/end of the function increases post-RA scheduler's ability to move instructions (that only depend on argument registers) before any of the callee-save stores This change can cause an increase in instructions if the original local stack SP decrement could be folded into the first store to the stack. This occurs when the first local stack store is to stack offset 0. In this case we are trading off one more sub instruction for one fewer sub micro-op (along with benefits (2) and (3) above).

Original patch from Fulvio Esposito (fulvio.esposito@outlook.com) - D11781 Applied with tweaks - D19412 Change-Id: I301111f0075de93dd8129416e06babc195aa936b llvm-svn: 268734
* [mips] Correct the ordering of HI/LO pairs in the relocation table.Daniel Sanders2016-05-064-302/+674
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: There seems to have been a misunderstanding as to the meaning of 'offset' in the rules laid down by our ABI. The previous code believed that 'offset' meant the offset within the section that the relocation is applied to. However, it should have meant the offset from the symbol used in the relocation expression. This patch adds two fields to ELFRelocationEntry and uses them to correct the order of relocations for MIPS. These fields contain: * The original symbol before shouldRelocateWithSymbol() is considered. This ensures that R_MIPS_GOT16 is able to correctly distinguish between local and external symbols, allowing us to tell whether %got() requires a matching %lo() or not (local symbols require one, external symbols don't). It also prevents confusing cases where the fuzzy matching rules cause things like %hi(foo)/%lo(foo+3) and %hi(bar)/%lo(bar+1) to swap their %lo()'s. * The original offset before shouldRelocateWithSymbol() is considered. The existing Addend field is always zero when the object uses in place addends (because it's already moved it to the encoding) but MIPS needs to use the original offset to ensure that the linker correctly calculates the carry-in bit for %hi() and %got(). IAS ensures that unmatchable %hi()/%got() relocations are placed at the end of the table to ensure that the linker rejects the table (we're unable to report such errors directly). The alternatives to this risk accidental matching against inappropriate relocations which may silently compute incorrect values due to an incorrect carry bit between the %lo() and %hi()/%got().

This is used in convertToMCInst to set default values in MCInst. Previously if you wanted to set default value for operand you had to create custom converter method. With this change it is possible to use standard converters even when optional operands presented.
