-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
2013-03-22Fix the invalid opcode for Mips branch instructions in the assemblerJack Carter
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.

2013-03-21Remove the G8RC_NOX0_and_GPRC_NOR0 PPC register classHal Finkel
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
2013-03-21Add TableGen ctags(1) emitter and helper script.Sean Silva
To use this in conjunction with exuberant ctags to generate a single combined tags file, run tblgen first and then $ ctags --append [...] Since some identifiers have corresponding definitions in C++ code, it can be useful (if using vim) to also use cscope, and :set cscopetagorder=1 so that :tag X will preferentially select the tablegen symbol, while :cscope find g X will always find the C++ symbol.

2013-03-21Always forward 'resume' instructions to the outter landing pad.Bill Wendling
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. <rdar://problem/13360379> & PR15555 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177680 91177308-0d34-0410-b5e6-96231b3b80d8

Thanks to Jakob for isolating the underlying problem from the test case in r177423.

2013-03-21This patch enables the Mips .set directive to define aliasesJack Carter
The .set directive in the Mips the assembler can be used to set the value of a symbol to an expression. This changes the symbol's value and type to conform to the expression's. Syntax: .set symbol, expression This patch implements the parsing of the above syntax and enables the parser to use defined symbols when parsing operands.

2013-03-21Implement builtin_{setjmp/longjmp} on PPCHal Finkel
This implements SJLJ lowering on PPC, making the Clang functions __builtin_{setjmp/longjmp} functional on PPC platforms. The implementation strategy is similar to that on X86, with the exception that a branch-and-link variant is used to get the right jump address. Credit goes to Bill Schmidt for suggesting the use of the unconditional bcl form (instead of the regular bl instruction) to limit return-address-cache pollution. Benchmarking the speed at -O3 of: static jmp_buf env_sigill; void foo() { __builtin_longjmp(env_sigill,1); } main() { ... for (int i = 0; i < c; ++i) { if (__builtin_setjmp(env_sigill)) { goto done; } else { foo(); } done:; } ... } vs. the same code using the libc setjmp/longjmp functions on a P7 shows that this builtin implementation is ~4x faster with Altivec enabled and ~7.25x faster with Altivec disabled. This comparison is somewhat unfair because the libc version must also save/restore the VSX registers which we don't yet support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177666 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-21Add support for spilling VRSAVE on PPCHal Finkel
Although there is only one Altivec VRSAVE register, it is a member of a register class, and we need the ability to spill it. Because this register is normally callee-preserved and handled by special code this has never before been necessary. However, this capability will be required by a forthcoming commit adding SjLj support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177654 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-21Correct PPC FRAMEADDR lowering using a pseudo-registerHal Finkel
The old code used to lower FRAMEADDR tried to replicate the logic in the real frame-lowering code that determines whether or not the frame pointer (r31) will be used. When it seemed as through the frame pointer would not be used, the stack pointer (r1) was used instead. Unfortunately, because the stack size is not yet known, this does not work. Instead, this change introduces new always-reserved pseudo-registers (FP and FP8) that are replaced during prologue insertion with the real frame-pointer register (either r1 or r31). It is important that this intrinsic always return a valid frame address because it is used by Clang to store the frame address as part of code generation for __builtin_setjmp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177653 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-21Avoid NEON SP-FP unless unsafe-math or DarwinRenato Golin
NEON is not IEEE 754 compliant, so we should avoid lowering single-precision floating point operations with NEON unless unsafe-math is turned on. The equivalent VFP instructions are IEEE 754 compliant, but in some cores they're much slower, so some archs/OSs might still request it to be on by default, such as Swift and Darwin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177651 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-21Hoist the definition of getTypeSizeInBits to be inlinable and in theChandler Carruth
header. This method is called in the hot path for *many* passes, SROA is what caught my interest. A common pattern is that which branch of the switch should be taken is known in the callsite and so it is a very good candidate for inlining and simplification. Moving it into the header allows the optimizer to fold a lot of boring, repeatitive code in callers of this routine. I'm seeing pretty significant speedups in parts of SROA and I suspect other passes will see similar speedups if they end up working with type sizes frequently. I've not seen any significant growth of the binaries as a consequence, but let me know if you see anything suspicious here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177632 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-21[SROA] Prefix names using a custom IRBuilder inserter.Chandler Carruth
The key part of this is ensuring that name prefixes remain in a Twine form until we get to a point where we can nuke them under NDEBUG. This is tricky using the old APIs as they played fast and loose with Twine, which is prone to serious error. The inserter is much cleaner as it is actually in the call stack leading to the setName call, and so has a good opportunity to prepend the prefix. This matters more than you might imagine because most runs over an alloca find a single partition, and rewrite 3 or 4 instructions referring to it. As a consequence doing this lazily and exclusively with Twine allows the optimizer to delete more of it and shaves another 2% to 3% off of the release build's SROA run time for PR15412. I also think the APIs are cleaner, and the use of Twine is more reliable, so I consider it a win-win despite the churn required to reach this state. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177631 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-21Move library call prototype attribute inference to functionattrsMeador Inge
The simplify-libcalls pass implemented a doInitialization hook to infer function prototype attributes for well-known functions. Given that the simplify-libcalls pass is going away *and* that the functionattrs pass is already in place to deduce function attributes, I am moving this logic to the functionattrs pass.
