Rozycki Date: Fri, 25 Jul 2014 17:57:06 +0000 (+0100) Subject: MIPS: Respect the "set mips compression" command X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d54398a79e97eff8f51aed2035cb513cdc4fb319;p=binutils-gdb.git MIPS: Respect the "set mips compression" command This fixes gdbarch matching, making sure one for the opposite compressed ISA variation is not chosen. That in turn makes "set mips compression" work; right now the setting sticks to the initial value, either inferred from the ELF header of the binary first loaded or the default value if no binary has been used. This only affects debugging with no symbol table available or no binary chosen at all, as otherwise symbol annotations determine the compressed ISA variation. * mips-tdep.c (mips_gdbarch_init): Also check the compressed ISA variation in gdbarch matching. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 47205a1cbb0..a73b37f25aa 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2014-07-25 Maciej W.
