2011-01-14Add a possibility to switch between CFI directives- and table-based frame ↵Anton Korobeynikov
description emission. Currently all the backends use table-based stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123476 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-10Rename TargetFrameInfo into TargetFrameLowering. Also, put couple of FIXMEs ↵Anton Korobeynikov
and fixes here and there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123170 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-07Do not model all INLINEASM instructions as having unmodelled side effects.Evan Cheng
Instead encode llvm IR level property "HasSideEffects" in an operand (shared with IsAlignStack). Added MachineInstrs::hasUnmodeledSideEffects() to check the operand when the instruction is an INLINEASM. This allows memory instructions to be moved around INLINEASM instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123044 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-02split dom frontier handling stuff out to its own DominanceFrontier header,Chris Lattner
so that Dominators.h is *just* domtree. Also prune #includes a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122714 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-19Add missing standard headers. Patch by Joerg Sonnenberger!Nick Lewycky
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122193 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-13remove the verbose-asm "constant pool double" comments that we were printingChris Lattner
for each constant pool entry. Using WriteTypeSymbolic here takes time proportional to the size of the module, for each constant pool entry. This speeds up -verbose-asm llc on 252.eon (a random testcase at my disposal) from 4.4s to 2.137s. llc takes 2.11s with asm-verbose off, so this is now a pretty reasonable cost for verbose comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121691 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-09DW_FORM_data1 may not provide sufficient room for vtable index, use _udata ↵Devang Patel
instead. This fixes radar 8730409. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121323 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-06Undefined value in reg 0 may need a marker to identify end of source range.Devang Patel
This will be used to truncate live range of DBG_VALUE instruction by register allocator and friends. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121061 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-06Second try at making direct object emission produce the same resultsRafael Espindola
as llc + llvm-mc. This time ELF is not changed and I tested that llvm-gcc bootstrap on darwin10 using darwin9's assembler and linker. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121006 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-06Revert previous two patches while I try to find out how to make bothRafael Espindola
linux and darwin assemblers happy :-( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121004 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-06Add an EmitAbsValue helper method and use it in cases where we want to be sureRafael Espindola
that no relocations are used (on MochO). Fixes llc producing different output from llc + llvm-mc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121000 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-20Move some more hooks to TargetFrameInfoAnton Korobeynikov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119904 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Move getInitialFrameState() to TargetFrameInfoAnton Korobeynikov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119754 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-18Change CodeGen to use .loc directives. This produces a lot more readable outputRafael Espindola
and testing is easier. A good example is the unknown-location.ll test that now can just look for ".loc 1 0 0". We also don't use a DW_LNE_set_address for every address change anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119613 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17With the newly simplified SourceMgr interfaces and the generalizedChris Lattner
SrcMgrDiagHandler, we can improve clang diagnostics for inline asm: instead of reporting them on a source line of the original line, we can report it on the correct line wherever the string literal came from. For something like this: void foo() { asm("push %rax\n" ".code32\n"); } we used to get this: (note that the line in t.c isn't helpful) t.c:4:7: error: warning: ignoring directive for now asm("push %rax\n" ^ <inline asm>:2:1: note: instantiated into assembly here .code32 ^ now we get: t.c:5:8: error: warning: ignoring directive for now ".code32\n" ^ <inline asm>:2:1: note: instantiated into assembly here .code32 ^ Note that we're pointing to line 5 properly now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119488 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17now that AsmPrinter::EmitInlineAsm is factored right, we can eliminate theChris Lattner
cookie argument to the SourceMgr diagnostic stuff. This cleanly separates LLVMContext's inlineasm handler from the sourcemgr error handling definition, increasing type safety and cleaning things up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119486 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17rearrange how the handler in SourceMgr is installed, eliminating the use of Chris Lattner
the cookie argument to setDiagHandler git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119483 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17refactor the interface to EmitInlineAsm a bit, no functionality change.Chris Lattner
