| * | [LSR] Don't try and create post-inc expressions on non-rotated loops | James Molloy | 2016-08-15 | 1 | -0/+1 |
| | | | | | | | | | | | | | | | | If a loop is not rotated (for example when optimizing for size), the latch is not the backedge. If we promote an expression to post-inc form, we not only increase register pressure and add a COPY for that IV expression but for all IVs! Motivating testcase: void f(float *a, float *b, float *c, int n) { while (n-- > 0) *c++ = *a++ + *b++; } It's imperative that the pointer increments be located in the latch block and not the header block; if not, we cannot use post-increment loads and stores and we have to keep both the post-inc and pre-inc values around until the end of the latch which bloats register usage. llvm-svn: 278658 | ||||
| * | [Hexagon] Generate hardware loop when loop has a critical edge | Brendon Cahoon | 2015-05-13 | 1 | -0/+58 |
| The hardware loop pass should try to generate a hardware loop instruction when the original loop has a critical edge. Differential Revision: http://reviews.llvm.org/D9678 llvm-svn: 237258 | |||||
