MIPS: Sort out mm_isBranchInstr.

2014-05-23T13:12:37+00:00

mm_isBranchInstr() did reside in the math emu code even though it logically is separate and also is used outside the math emu code. In addition GCC 4.9.0 leaves the following unnnecessarily bloated function body for a non-microMIPS configuration: : 105c: afa50004 sw a1,4(sp) 1060: afa60008 sw a2,8(sp) 1064: afa7000c sw a3,12(sp) 1068: 03e00008 jr ra 106c: 00001021 move v0,zero which stores arguments that are never going to be used on the stack frame. Move mm_isBranchInstr() from cp1emu.c to branch.c, then split mm_isBranchInstr() into a __mm_isBranchInstr() core and a mm_isBranchInstr() wrapper inline function which only invokes __mm_isBranchInstr() on microMIPS configurations. This shaves off 112 bytes off the kernel and improves code flow a bit. Signed-off-by: Ralf Baechle

MIPS Kprobes: Refactor branch emulation

2011-12-07T22:04:03+00:00

This patch refactors MIPS branch emulation code so as to allow skipping delay slot instruction in case of branch likely instructions when branch is not taken. This is useful for keeping the code common for use cases like kprobes where one would like to handle the branch instructions keeping the delay slot instuction also in picture for branch likely instructions. Also allow emulation when instruction to be decoded is not at pt_regs->cp0_epc as in case of kprobes where pt_regs->cp0_epc points to the breakpoint instruction. The patch also exports the function for modules.
