* [NVPTXAsmPrinter] do not print .align on function headersJingyue Wu2015-03-121-0/+1
| | | | | | | | | | | | | | | | | | | Summary: PTX does not allow .align directives on function headers. Fixes PR21551.

* Don't print labels that on ELF are never used.Rafael Espindola2015-03-111-16/+14

* Print section start labels when first switching to the section.Rafael Espindola2015-03-111-0/+4
| | | | | | | This is less brittle and avoids polluting the start of the file with every debug section. llvm-svn: 231898
* Add missing section symbol to COFF's .debug_types.dwo.Rafael Espindola2015-03-101-1/+1
| | | | | | | | | Should bring the cygwin bots back. I added a triple to the test that was failing so that it would have failed on Linux. llvm-svn: 231882
* Create symbols marking the start of a section earlier.Rafael Espindola2015-03-103-77/+99
| | | | | | | | | This lets us pass the symbol to the constructor and avoid the mutable field. This also opens the way for outputting the symbol only when needed, instead of outputting them at the start of the file. llvm-svn: 231859

* Make constant arrays that are passed to functions as const.Benjamin Kramer2015-03-071-5/+4
| | | | | | | | In theory this allows the compiler to skip materializing the array on the stack. In practice clang often fails to do that, but that's a different story. NFC. llvm-svn: 231571
* Use the generic Lfunc_begin label on ppc.Rafael Espindola2015-03-051-0/+1

* Centralize handling of the eh_begin and eh_end labels.Rafael Espindola2015-02-271-0/+6
| | | | | | | | | | This removes a bit of duplicated code and more importantly, remembers the labels so that they don't need to be looked up by name. This in turn allows for any name to be used and avoids a crash if the name we wanted was already taken. llvm-svn: 230772
* [MC] Use the non-EH register mapping in the debug_frame section.Frederic Riss2015-02-261-4/+20
| | | | | | | | | | | | | | | | | | | | On 32bits x86 Darwin, the register mappings for the eh_frane and debug_frame sections are different. Thus the same CFI instructions should result in different registers in the object file. The problem isn't target specific though, but it requires that the mappings for EH register numbers be different from the standard Dwarf one. The patch looks a bit clumsy. LLVM uses the EH mapping as canonical for everything frame related. Thus we need to do a double conversion EH -> LLVM -> Non-EH, when emitting the debug_frame section. Fixes PR22363.

* Use std::bitset for SubtargetFeaturesMichael Kuperstein2015-02-192-13/+19
| | | | | | | | | | | Previously, subtarget features were a bitfield with the underlying type being uint64_t. Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset. No functional change.

| | | | | | | | | | | | | | | | regressions for LLDB on Linux. Rafael indicated on lldb-dev that we should just go ahead and revert these but that he wasn't at a computer. The patches backed out are as follows: r228980: Add support for having multiple sections with the name and ... r228889: Invert the section relocation map. r228888: Use the existing SymbolTableIndex intsead of doing a lookup. r228886: Create the Section -> Rel Section map when it is first needed.

Use the flags to compute the SectionKind. This removes a lot of guessing and boilerplate from the MCSectionELF construction. llvm-svn: 227476
