Oliver Stannard bb804ee909 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211272 91177308-0d34-0410-b5e6-96231b3b80d8		2014-06-19 15:39:33 +00:00
