| | | | | | | | | | | | | | | | | | | | | | | | | | | reserving a physical register ($gp or $28) for that purpose. This will completely eliminate loads that restore the value of $gp after every function call, if the register allocator assigns a callee-saved register, or eliminate unnecessary loads if it assigns a temporary register. example: .cpload $25 // set $gp. ... .cprestore 16 // store $gp to stack slot 16($sp). ... jalr $25 // function call. clobbers $gp. lw $gp, 16($sp) // not emitted if callee-saved reg is chosen. ... lw $2, 4($gp) ... jalr $25 // function call. lw $gp, 16($sp) // not emitted if $gp is not live after this instruction. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151402 91177308-0d34-0410-b5e6-96231b3b80d8

* Mips MC object code emission improvements:Bruno Cardoso Lopes2011-11-11
| | | | | | | | | | "With this patch we can now generate runnable Mips code through LLVM direct object emission. We have run numerous simple programs, both C and C++ and with -O0 and -O3 from the output. The code is not production ready, but quite useful for experimentation." Patch and message by Jack Carter git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144414 91177308-0d34-0410-b5e6-96231b3b80d8

* One more patch towards JIT support for Mips.Bruno Cardoso Lopes2011-09-14
| | | | | | | | | | | | | | - Add TSFlags for the instruction formats. The idea here is to use as much encoding as possible from getBinaryCodeForInstr, and having TSFLags formats for that would make it easier to encode most part of the instructions (since Mips encodings are pretty straightforward) - Improve the mips mechanism for compilation callback - Add Mips specific code for invalidating the instruction cache - Next patch will address wrong tablegen encoding Commit msg added by my own but the patch is from Sasa Stankovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139688 91177308-0d34-0410-b5e6-96231b3b80d8

* RISC architectures get their memory operand folding for free.Jakob Stoklund Olesen2010-07-11
| | | | | | | | The only folding these load/store architectures can do is converting COPY into a load or store, and the target independent part of foldMemoryOperand already knows how to do that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108099 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a DebugLoc parameter to TargetInstrInfo::InsertBranch(). ThisStuart Hastings2010-06-17
| | | | | | | | | | | | | addresses a longstanding deficiency noted in many FIXMEs scattered across all the targets. This effectively moves the problem up one level, replacing eleven FIXMEs in the targets with eight FIXMEs in CodeGen, plus one path through FastISel where we actually supply a DebugLoc, fixing Radar 7421831. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106243 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-14
| | | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-11
| | | | | | | | | | Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8
