Module Name: src
Committed By: phx
Date: Thu Jan 28 19:01:33 UTC 2010
Modified Files:
src/sys/arch/powerpc/powerpc: db_disasm.c
Log Message:
Fixed some more instructions and their operands.
Print the register-indirect operand with displacement in load/store
instructions as d(rN).
Conditional branches are printed with their simplified mnemonic (i.e.
beq instead of bc x,y). Also append the branch-prediction flag +/-i.
Print real labels for 16-bit branches instead of just an offset.
Use the simplified mnemonic cmpw and cmpd, and much more enhancements...
