- Subject: [PATCH 11/20] MIPS/GAS: Remove dead base register code
Hi,
This change removes dead code to handle "(4)", "(5)" and "(-)" base
register format specifiers. They are nowhere used in opcode tables nor in
macro_build() invocations and "4" and "5" have been since taken for use as
some DSP ASE immediate specifiers.

gas/
* config/tc-mips.c (mips_ip)['(']: Don't let '4', '5' or '-'
as a base register specifier.
OK to apply?
Maciej
