[PATCH GCC][7/7]Merge adjacent memset builtin partitions

2017-10-05 Thread Bin Cheng
Hi, This patch merges adjacent memset builtin partitions if possible. It is a useful special case optimization transforming below code: #define M (256) #define N (512) struct st { int a[M][N]; int c[M]; int b[M][N]; }; void foo (struct st *p) { for (unsigned i = 0; i < M; ++i) {
