2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-09-14target-mips: fix single-steppingNathan Froyd
Single-stepping branches on MIPS didn't work right, because the generation of EXCP_DEBUG happened after the generation of the code to exit the current TB. That is, given the code: bne v0,v1,target nop ... target: addu v0,v0,v1 1: when you single-stepped through the NOP, execution wouldn't actually halt until you reached the label `1'. This patch corrects that and also changes single-stepping so that a branch and its delay slot are executed as one instruction for the purposes of single-stepping. This behavior is comparable to what other MIPS tools (e.g. MIPSsim with MDI) do. GDB avoids placing breakpoints in branch delay slots, so this change doesn't break anything on the GDB side.

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-08-25target-mips: fix conditional moves off fp condition codesNathan Froyd
Conditional moves off fp condition codes were using the result of get_fp_bit to isolate and test the relevant condition code. However, get_fp_bit returns the bit number of the condition code, not a bitmask. (Compare the use of get_fp_bit in gen_compute_branch1, for instance.) Fixed by shifting a bitmask into place using the result of get_fp_bit in the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).
