ping x3 : latch mem to reg before multi-access in convert_move

2012-06-23 Thread Olivier Hainque
Hello, ping # 3 for http://gcc.gnu.org/ml/gcc-patches/2012-04/msg00298.html This is related to convert-move possibly emitting a sequence with multiple accesses to one input, triggering multiple memory accesses when that input happens to be a mem. > The original problem we had with this was the i

Coverage unlinking

2012-06-23 Thread Nathan Sidwell
This patch changes the coverage unlinking to be less aggressive. As David pointed out, when experimenting with random optimization options along side -fuse-coverage and -frandom-seed, it is inconvenient for gcc to remove the coverage data file. The reason it was doing so, is because -frandom-s

[PATCH 0/3] Fix target/53749

2012-06-23 Thread Richard Henderson
The problem being addressed is that expand_mult expects that any mode that supports multiply also support shift. In practice that's a fairly valid assumption -- I've never seen an ISA for which this didn't hold. However, it means that if you jump through hoops in the backend to provide a (vector)
