* [mips] not instruction aliasSimon Dardis2016-11-161-0/+2
| | | | | | | | | | | | This patch adds the single operand form of the not alias to microMIPS and MIPS along with additional tests. This partially resolves PR/30381.

* [mips] Fix c.<cc>.<fmt> instruction definition.Simon Dardis2016-09-092-32/+32
| | | | | | | | | | | | | | | | As part of this effort, remove MipsFCmp nodes and use tablegen patterns rather than custom lowering through C++. Unexpectedly, this improves codesize for microMIPS as previous floating point setcc expansions would materialize 0 and 1 into GPRs before using the relevant mov[tf].[sd] instruction. Now $zero is used directly.

* [mips] Don't derive the default ABI from the CPU in the backend.Daniel Sanders2016-06-232-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: The backend has no reason to behave like a driver and should generally do as it's told (and error out if it can't) instead of trying to figure out what the API user meant. The default ABI is still derived from the arch component as a concession to backwards compatibility. API-users that previously passed an explicit CPU and a triple that was inconsistent with the CPU (e.g. mips-linux-gnu and mips64r2) may get a different ABI to what they got before. However, it's expected that there are no such users on the basis that CodeGen has been asserting that the triple is consistent with the selected ABI for several releases. API-users that were consistent or passed '' or 'generic' as the CPU will see no difference.

| | | | | | | | | | | | | | | | | | | | | | | | Summary: The bugs were: * append, prepend, and balign were not tested * balign takes a uimm2 not a uimm5. * drotr32 was correctly implemented with a uimm5 but the tests expected '52' to be valid. * li/la were implemented with a uimm5 instead of simm32. simm32 isn't completely correct either but I'll fix that when I get to simm32. A notable omission are some of the shift instructions. Several of these have been implemented using a single uimm6 instruction (rather than two uimm5 instructions and a CodeGen-only uimm6 pseudo). These will be updated in the uimm6 patch.

* [mips] Remap move as or.Vasileios Kalintiris2015-08-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch remaps the assembly idiom 'move' to 'or' instead of 'daddu' or 'addu'. The use of addu/daddu instead of or as move was highlighted as a performance issue during the analysis of a recent 64bit design. Originally move was encoded as 'or' by binutils but was changed for the r10k cpu family due to their pipeline which had 2 arithmetic units and a single logical unit, and so could issue multiple (d)addu based moves at the same time but only 1 logical move. This patch preserves the disassembly behaviour so that disassembling a old style (d)addu move still appears as move, but assembling move always gives an or Patch by Simon Dardis.

* [mips] Correct section alignments and EntrySizes for .bss, .text, .data, ↵Daniel Sanders2014-07-141-21/+20
| | | | | | | | | | | | | | | | | | | .reginfo, .MIPS.options, and .MIPS.abiflags Summary: .bss, .text, and .data are at least 16-byte aligned. .reginfo is 4-byte aligned and has a 24-byte EntrySize. .MIPS.abiflags has an 24-byte EntrySize. .MIPS.options is 8-byte aligned and has 1-byte EntrySize. Using a 1-byte EntrySize for .MIPS.options seems strange because the records are neither 1-byte long nor fixed-length but this matches the value that GAS emits.

This patch implements mips.abiflags section and provides test cases for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212519 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | Summary: This instruction is re-encoded in MIPS32r6/MIPS64r6 without changing the restrictions. We hadn't implemented it for earlier ISA's so it has been added to those too.
