[mips] Add -mabicalls/-mno-abicalls to the driver Based on a patch by Matheus Almeida. I've added testcases and fixed a bug where the options weren't passed on to GAS. llvm-svn: 215204

[mips] Invert the abicalls feature bit to be noabicalls so that it's possible for -mno-abicalls to take effect. Also added the testcase that should have been in r215194. This behaviour has surprised me a few times now. The problem is that the generated MipsSubtarget::ParseSubtargetFeatures() contains code like this: if ((Bits & Mips::FeatureABICalls) != 0) IsABICalls = true; so '-abicalls' means 'leave it at the default' and '+abicalls' means 'set it to true'. In this case, (and the similar -modd-spreg case) I'd like the code to be IsABICalls = (Bits & Mips::FeatureABICalls) != 0; or possibly: if ((Bits & Mips::FeatureABICalls) != 0) IsABICalls = true; else IsABICalls = false; and preferably arrange for 'Bits & Mips::FeatureABICalls' to be true by default (on some triples). llvm-svn: 215211

[mips] Introducing option -mabs=[legacy/2008] In patch r205628 using abs.[ds] instruction is forced, as they should behave in accordance with flags Has2008 and ABS2008. Unfortunately for revisions prior mips32r6 and mips64r6, abs.[ds] is not generating correct result when working with NaNs. To generate a sequence which always produce a correct result but also to allow user more control on how his code is compiled, option -mabs is added where user can choose legacy or 2008. By default legacy mode is used on revisions prior R6. Mips32r6 and mips64r6 use abs2008 mode by default.

[mips] Compact branch policy setting. This patch adds the commandline option -mcompact-branches={never,optimal,always), which controls how LLVM generates compact branches for MIPSR6 targets. By default, the compact branch policy is 'optimal' where LLVM will generate the most appropriate branch for any situation. The 'never' and 'always' policy will disable or always generate compact branches wherever possible respectfully.

[mips] Spectre variant two mitigation for MIPSR2 This patch provides mitigation for CVE-2017-5715, Spectre variant two, which affects the P5600 and P6600. It provides the option -mindirect-jump=hazard, which instructs the LLVM backend to replace indirect branches with their hazard barrier variants. This option is accepted when targeting MIPS revision two or later. The migitation strategy suggested by MIPS for these processors is to use two hazard barrier instructions. 'jalr.hb' and 'jr.hb' are hazard barrier variants of the 'jalr' and 'jr' instructions respectively. These instructions impede the execution of instruction stream until architecturally defined hazards (changes to the instruction stream, privileged registers which may affect execution) are cleared. These instructions in MIPS' designs are not speculated past. These instructions are used with the option -mindirect-jump=hazard when branching indirectly and for indirect function calls. These instructions are defined by the MIPS32R2 ISA, so this mitigation method is not compatible with processors which implement an earlier revision of the MIPS ISA. Implementation note: I've opted to provide this as an -mindirect-jump={hazard,...} style option in case alternative mitigation methods are required for other implementations of the MIPS ISA in future, e.g. retpoline style solutions.
