Subject: * config/tc-mips.c (macro_build_jalr): Make sure we generate
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f21f824289798324355d9f6521a93b598bf883a9;p=binutils-gdb.git

* config/tc-mips.c (macro_build_jalr): Make sure we generate
the fix-up against on the right frag.
(s_cpsetup): Likewise.  Parse third argument as expression, to
handle global symbols and forward/backward labels correctly.
