This is an unofficial mirror that nobody from the GCC project is involved with. Sending pull requests here is a waste of time. Please see https://gcc.gnu.org/contribute.html for how to contribute to GCC, thanks. (However, I have no idea what this patch is supposed to be for, and it doesn't look likely to be accepted.) |

This patch moves the move-immediate splitter after the regular ones so
that it has lower precedence, and updates its constraints.
For
int f3 (void) { return 0x11000000; }
int f3_2 (void) { return 0x12345678; }
we now generate:
* with -O2 -mcpu=cortex-m0 -mpure-code:
f3:
movs r0, #136
lsls r0, r0, gcc-mirror#21
bx lr
f3_2:
movs r0, gcc-mirror#18
lsls r0, r0, gcc-mirror#8
adds r0, r0, gcc-mirror#52
lsls r0, r0, gcc-mirror#8
adds r0, r0, gcc-mirror#86
lsls r0, r0, gcc-mirror#8
adds r0, r0, #121
bx lr
* with -O2 -mcpu=cortex-m23 -mpure-code:
