Ulrich Weigand c1f4a4b264 [MC/DWARF] Support .debug_frame / .debug_line code alignment factors ... I've been comparing the object file output of LLVM's integrated assembler against the external assembler on PowerPC, and one area where differences still remain are in DWARF sections. In particular, the GNU assembler generates .debug_frame and .debug_line sections using a code alignment factor of 4, since all PowerPC instructions have size 4 and must be aligned to a multiple of 4. However, current MC code hard-codes a code alignment factor of 1. This patch changes this by adding a "minimum instruction alignment" data element to MCAsmInfo and using this as code alignment factor. This requires passing a MCContext into MCDwarfLineAddr::Encode and MCDwarfLineAddr::EncodeAdvanceLoc. Note that one caller, MCDwarfLineAddr::Write, didn't actually have that information available. However, it turns out that this routine is in fact never used in the whole code base, so the patch simply removes it. If it turns out to be needed again at a later time, it could be re-added with an updated interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183834 91177308-0d34-0410-b5e6-96231b3b80d8		2013-06-12 14:46:54 +00:00

Disassembler	This patch adds support for FPINST/FPINST2 as operands to vmsr/vmrs. These are optional registers that may be supported some ARM implementations to aid with resolution of floating point exceptions. The manual pages for vmsr and vmrs do not detail their use. Encodings and other information can be found in ARM Architecture Reference Manual section F, chapter 6, paragraph 3.	2013-06-11 09:39:51 +00:00
