Revert r177543: Add timing of the IR parsing code with a new

2013-03-22T02:20:34Z

-time-ir-parsing flag This breaks the layering of the Support library. We can't add an implementation side to IRReader because it refers directly to entities only accessible as part of the IR, AsmParser, and BitcodeReader libraries. It can only be used in a context where all of those libraries will be available. We'll need to find some other way to get this functionality, and hopefully solve the long-standing layering problem of IRReader.h... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177695 91177308-0d34-0410-b5e6-96231b3b80d8

Fix the invalid opcode for Mips branch instructions in the assembler

2013-03-22T00:29:10Z

For mips a branch an 18-bit signed offset (the 16-bit offset field shifted left 2 bits) is added to the address of the instruction following the branch (not the branch itself), in the branch delay slot, to form a PC-relative effective target address. Previously, the code generator did not perform the shift of the immediate branch offset which resulted in wrong instruction opcode. This patch fixes the issue.

This patch that enables the Mips assembler to use symbols for offset for instructions

2013-03-22T00:05:30Z

This patch uses the generated instruction info tables to identify memory/load store instructions. After successful matching and based on the operand type and size, it generates additional instructions to the output.

Remove the G8RC_NOX0_and_GPRC_NOR0 PPC register class

2013-03-21T23:45:03Z

As Jakob pointed out in his review of r177423, having a shared ZERO register between the 32- and 64-bit register classes causes this odd G8RC_NOX0_and_GPRC_NOR0 class to be created. As recommended, this adds a ZERO8 register which differentiates the 32- and 64-bit zeros. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177683 91177308-0d34-0410-b5e6-96231b3b80d8

Always forward 'resume' instructions to the outter landing pad.

2013-03-21T23:30:12Z

How did this ever work? Basically, if you have a function that's inlined into the caller, it may not have any 'call' instructions, but any 'resume' instructions it may have should still be forwarded to the outer (caller's) landing pad. This requires that all of the 'landingpad' instructions in the callee have their clauses merged with the caller's outer 'landingpad' instruction (hence the bit of ugly code in the `forwardResume' method). Testcase in a follow commit to the test-suite repository. & PR15555 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177680 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a register-class comparison bug in PPCCTRLoops

2013-03-21T23:23:34Z

Thanks to Jakob for isolating the underlying problem from the test case in r177423. The original commit had introduced asymmetric copy operations, but these turned out to be a work-around to the real problem (the use of == instead of hasSubClassEq in PPCCTRLoops). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177679 91177308-0d34-0410-b5e6-96231b3b80d8
