2011-06-10Ensure that EmitGlobalVariable is correctly differentiating between declarationsChad Rosier
and definitions when emitting global variables. This was causing global declarations to be emitted as if they were definitions. Fixes <rdar://problem/9429892>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132825 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-28When generating code for Win64 EH, emit StartProc and EndProc directives.Charles Davis
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132250 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-28Fix the root cause of the bootstrap failure:Rafael Espindola
There was no way to check if a given register/mode pair was valid. We now return an error code (-2) instead of asserting. If anyone thinks that an assert at this point is really needed, we can autogen a hasValidDwarfRegNum instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132236 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-27Stub out support for Win64-style exceptions. Note that this is merely usingCharles Davis
the Win64 EH mechanism to implement GCC-style exceptions. LLVM supports hardly anything else at this point! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132234 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-27Fix a regression I recently introduced by removing DwarfRegNum ofRafael Espindola
subregisters: When a value is in a subregister, at least report the location as being the superregister. We should extend the .td files to encode the bit range so that we can produce a DW_OP_bit_piece. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132224 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-25Replace the -unwind-tables option with a per function flag. This is moreRafael Espindola
LTO friendly as we can now correctly merge files compiled with or without -fasynchronous-unwind-tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132033 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-10Produce a __debug_frame section on darwin ARM when appropriate.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131151 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-10Use .cfi_sections to put the unwind info in .debug_frame when possible. WithRafael Espindola
this clang will use .debug_frame in, for example, clang -g -c -m32 test.c This matches gcc's behaviour. It looks like .debug_frame is a bit bigger than .eh_frame, but has the big advantage of not being allocated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131140 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
