Keith Walker	ea9483f847	[DWARF] Add CIE header fields address_size and segment_size when generating dwarf-4 ... The DWARF-4 specification added 2 new fields in the CIE header called address_size and segment_size. Create these 2 new fields when generating dwarf-4 CIE entries, print out the new fields when dumping the CIE and update tests Differential Revision: http://reviews.llvm.org/D9558 llvm-svn: 237145	2015-05-12 15:25:08 +00:00
Rafael Espindola	effdc7e981	Use CIE version 4 for dwarf4. ... According to http://www.dwarfstd.org/doc/DWARF4.pdf appendix F the CIE version for dwarf 4 is 4. llvm-svn: 235988	2015-04-28 13:55:31 +00:00
Oliver Stannard	f7693f4c1f	Emit DWARF3 call frame information when DWARF3+ debug info is requested ... Currently, llvm always emits a DWARF CIE with a version of 1, even when emitting DWARF 3 or 4, which both support CIE version 3. This patch makes it emit the newer CIE version when we are emitting DWARF 3 or 4. This will not reduce compatibility, as we already emit other DWARF3/4 features, and is worth doing as the DWARF3 spec removed some ambiguities in the interpretation of call frame information. It also fixes a minor bug where the "return address" field of the CIE was encoded as a ULEB128, which is only valid when the CIE version is 3. There are no test changes for this, because (as far as I can tell) none of the platforms that we test have a return address register with a DWARF register number >127. llvm-svn: 211272	2014-06-19 15:39:33 +00:00
