* CodeGen: split out the Win64Exception emitterSaleem Abdulrasool2014-09-011-33/+0
| | | | | | | Move the Windows unwind information emitter into a separate header. This is not related to DWARF based emission. NFC. llvm-svn: 216894
* Canonicalize header guards into a common format.Benjamin Kramer2014-08-131-2/+2
| | | | | | | | | | Add header guards to files that were missing guards. Remove #endif comments as they don't seem common in LLVM (we can easily add them back if we decide they're useful) Changes made by clang-tidy with minor tweaks. llvm-svn: 215558
* CodeGen: refactor DwarfExceptionSaleem Abdulrasool2014-06-111-129/+5
| | | | | | | | | | | | DwarfException served as a base class for exception handling directive emission. However, this is also used by other exception models (e.g. Win64EH). Rename this class to EHStreamer and split it out of DwarfException.h. NFC. Use the opportunity to fix up some of the documentation comments to match current LLVM style. Also rename some functions to conform better with current LLVM coding style. llvm-svn: 210622

* Add a MCTargetStreamer interface.Rafael Espindola2013-10-081-0/+3
| | | | | | | | | | | | | This patch fixes an old FIXME by creating a MCTargetStreamer interface and moving the target specific functions for ARM, Mips and PPC to it. The ARM streamer is still declared in a common place because it is used from lib/CodeGen/ARMException.cpp, but the Mips and PPC are completely hidden in the corresponding Target directories. I will send an email to llvmdev with instructions on how to use this. llvm-svn: 192181
* Revert "Give internal classes hidden visibility."Benjamin Kramer2013-09-111-4/+4
| | | | | | | It works with clang, but GCC has different rules so we can't make all of those hidden. This reverts commit r190534. llvm-svn: 190536
* Give internal classes hidden visibility.Benjamin Kramer2013-09-111-4/+4
| | | | | | Worth 100k on a linux/x86_64 Release+Asserts clang. llvm-svn: 190534
* Remove the MachineMove class.Rafael Espindola2013-05-131-1/+0
| | | | | | | | | | | | It was just a less powerful and more confusing version of MCCFIInstruction. A side effect is that, since MCCFIInstruction uses dwarf register numbers, calls to getDwarfRegNum are pushed out, which should allow further simplifications. I left the MachineModuleInfo::addFrameMove interface unchanged since this patch was already fairly big. llvm-svn: 181680
* Factor out type info emission into separate routine.Anton Korobeynikov2012-11-191-0/+3
| | | | | | | It turned out that ARM wants different layout of type infos. This is yet another patch in attempt to fix PR7187 llvm-svn: 168325

* Use .cfi_sections to put the unwind info in .debug_frame when possible. WithRafael Espindola2011-05-101-0/+3
| | | | | | | | | 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. llvm-svn: 131140

* Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe whatBill Wendling2010-05-141-2/+2
| | | | | | | | | the variable actually tracks. N.B., several back-ends are using "HasCalls" as being synonymous for something that adjusts the stack. This isn't 100% correct and should be looked into. llvm-svn: 103802

| | | | | | | The only thing left is LEB printing, which uses EmitRawText for now. llvm-svn: 100325
* change EH related stuff (other than EH_LABEL) to use MCSymbolChris Lattner2010-03-141-11/+4
| | | | | | | | | | | | | | | | instead of label ID's. This cleans up and regularizes a bunch of code and makes way for future progress. Unfortunately, this pointed out to me that JITDwarfEmitter.cpp is largely copy and paste from DwarfException/MachineModuleInfo and other places. This is very sad and disturbing. :( One major change here is that TidyLandingPads moved from being called in DwarfException::BeginFunction to being called in DwarfException::EndFunction. There should not be any functionality change from doing this, but I'm not an EH expert. llvm-svn: 98459

| | | | | | | | | | | | | Basically, this patch is working towards removing the hard-coded values that are output for the CIE. In particular, the CIE augmentation and the CIE augmentation size. Both of these should be calculated. In the process, I was able to make a bunch of code simpler. The encodings for the personality, LSDA, and FDE in the CIE are still not correct. They should be generated either from target-specific callbacks (blech!) or grokked from first-principles. llvm-svn: 81404
