[Bug target/34409] New: MIPS: Non-optimal DWARF frame data

Subject: [Bug target/34409] New: MIPS: Non-optimal DWARF frame data
Reply-to: gcc-bugzilla at gcc dot gnu dot org

We are emitting .eh_frame data with DW_CFA_def_cfa where we could emit
DW_CFA_def_cfa_register.  This makes the .eh_frame one byte larger per
occurence.

This appears to only be done for mips targets as a workaround for bugs in the
SGI assembler/linker.  For targets using GNU Binutils we don't need the
workround.
