2011-09-26Convert more tests over to the new atomic instructions. Eli Friedman
I did not convert Atomics-32.ll and Atomics-64.ll by hand; the diff is autoupgrade output. The wmb test is gone because there isn't any way to express wmb with the new atomic instructions; if someone really needs a non-asm way to write a wmb on Alpha, a platform-specific intrisic could be added. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140566 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-06Split the init.trampoline intrinsic, which currently combines GCC'sDuncan Sands
init.trampoline and adjust.trampoline intrinsics, into two intrinsics like in GCC. While having one combined intrinsic is tempting, it is not natural because typically the trampoline initialization needs to be done in one function, and the result of adjust trampoline is needed in a different (nested) function. To get around this llvm-gcc hacks the nested function lowering code to insert an additional parent variable holding the adjust.trampoline result that can be accessed from the child function. Dragonegg doesn't have the luxury of tweaking GCC code, so it stored the result of adjust.trampoline in the memory GCC set aside for the trampoline itself (this is always available in the child function), and set up some new memory (using an alloca) to hold the trampoline. Unfortunately this breaks Go which allocates trampoline memory on the heap and wants to use it even after the parent has exited (!). Rather than doing even more hacks to get Go working, it seemed best to just use two intrinsics like in GCC. Patch mostly by Sanjoy Das. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139140 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-18rip out a ton of intrinsic modernization logic from AutoUpgrade.cpp, which isChris Lattner
for pre-2.9 bitcode files. We keep x86 unaligned loads, movnt, crc32, and the target indep prefetch change. As usual, updating the testsuite is a PITA. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133337 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-03Fix wrong usages of CTR/MCTR where CTR8/MCTR8 was meant.Roman Divacky
- Check for MTCTR8 in addition to MTCTR when looking up a hazard. - When lowering an indirect call use CTR8 when targeting 64bit. - Introduce BCTR8 that uses CTR8 and use it on 64bit when expanding ISD::BRIND. The last change fixes PR8487. With those changes, we are able to compile a running "ls" and "sh" on FreeBSD/PowerPC64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132552 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-30Enable CFI on OS X.Rafael Espindola
Currently the output should be almost identical to the one produced by CodeGen to make the transition easier. The only two differences I know of are: * Some files get an extra advance loc of size 0. This will be fixed when relaxations are enabled. * The optimization of declaring an EH symbol as an external variable is not implemented. This is a subset of adding the nounwind attribute, so we if really this at -O0 we should probably do it at the IL level. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130623 91177308-0d34-0410-b5e6-96231b3b80d8

The code inserted by PPCTargetLowering::EmitInstrWithCustomInserter for ppc64 is wrong, and I don't know how to fix it.

2010-07-16Consider this function:Bill Wendling
void foo() { __builtin_unreachable(); } It will output the following on Darwin X86: _func1: Leh_func_begin0: pushq %rbp Ltmp0: movq %rsp, %rbp Ltmp1: Leh_func_end0: This prolog adds a new Call Frame Information (CFI) row to the FDE with an address that is not within the address range of the code it describes -- part is equal to the end of the function -- and therefore results in an invalid EH frame. If we emit a nop in this situation, then the CFI row is now within the address range. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108568 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-15Handle code gen for the unreachable instruction if it's the only instruction inBill Wendling
the function. We'll just turn it into a "trap" instruction instead. The problem with not handling this is that it might generate a prologue without the equivalent epilogue to go with it: $ cat t.ll define void @foo() { entry: unreachable } $ llc -o - t.ll -relocation-model=pic -disable-fp-elim -unwind-tables .section __TEXT,__text,regular,pure_instructions .globl _foo .align 4, 0x90 _foo: ## @foo Leh_func_begin0: ## BB#0: ## %entry pushq %rbp Ltmp0: movq %rsp, %rbp Ltmp1: Leh_func_end0: ...

2010-07-01Implement the "linker_private_weak" linkage type. This will be used forBill Wendling
Objective-C metadata types which should be marked as "weak", but which the linker will remove upon final linkage. However, this linkage isn't specific to Objective-C. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". Currently only supported on Darwin platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107433 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-24Eliminate the first have of the optimization which eliminates BRCONDDan Gohman
when the condition is constant. This optimization shouldn't be necessary, because codegen shouldn't be able to find dead control paths that the IR-level optimizer can't find. And it's undesirable, because it encourages bugpoint to leave "br i1 false" branches in its output. And it wasn't updating the CFG. I updated all the tests I could, but some tests are too reduced and I wasn't able to meaningfully preserve them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106748 91177308-0d34-0410-b5e6-96231b3b80d8
