Author: emaste Date: Tue Jul 19 00:47:00 2016 New Revision: 303016 URL: https://svnweb.freebsd.org/changeset/base/303016 Log: llvm-libunwind: use conventional (non-Darwin) X86 register numbers For historical reasons Darwin/i386 has ebp and esp swapped in the eh_frame register numbering. That is: Darwin Other Reg # eh_frame eh_frame DWARF ===== ======== ======== ===== 4 ebp esp esp 5 esp ebp ebp Although the UNW_X86_* constants are not supposed to be coupled to DWARF / eh_frame numbering they are currently conflated in LLVM libunwind, and thus we require the non-Darwin numbering.
