[Bug target/44606] Wrong SPE floating point during computation
--- Comment #7 from froydnj at gcc dot gnu dot org 2010-09-09 15:28 --- The problem is in the register allocator. What happens is that after register allocation, we have something like: r27:DF = [r11:SI] ... r27:SI = 0 ... and then the first def gets deleted because it's obviously dead code. I don't know why the register allocator chooses r27 for the SImode pseudo. Scheduling is necessary to trigger the bug, but it's not the problem. -- froydnj at gcc dot gnu dot org changed: What|Removed |Added CC||froydnj at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44606
[Bug bootstrap/45518] New: [4.6 regression] bootstrap failure on sparc64-unknown-linux-gnu
I'm seeing a bootstrap failure on the compile farm's gcc63 machine. I realize there've been several logs submitted to gcc-testresults from Laurent's autotesters, but those testers configured with somewhat different options than I did. I'm configuring with: --disable-lib{ssp,mudflap,gomp} --enable-languages=c --disable-nls --enable-threads=posix whereas Laurent passes --with-cpu=v8 and --disable-multilib. Bootstrapping fails starting at r163383, Bernd's 4-insn combine change, when configuring support libraries (libiberty, zlib, libdecnumber) for stage3. I double-checked subsequent revisions that fix other PRs from r163383 (e.g. r163546) and those did not help either. I tried --disable-multilib and/or --with-cpu=niagara and that did not help. I'm unsure of what other information to provide, but can provide more information on request. -- Summary: [4.6 regression] bootstrap failure on sparc64-unknown- linux-gnu Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: froydnj at gcc dot gnu dot org GCC build triplet: sparc64-unknown-linux-gnu GCC host triplet: sparc64-unknown-linux-gnu GCC target triplet: sparc64-unknown-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45518

Second, the problem Daniel mentioned concerning auto-inc/dec not doing the right thing is because of the cleverness of loop-unroll.c:analyze_iv_to_split_insn. It breaks the code shape that auto-inc/dec needs. (You can see its effects in the assembly above; the spurious move to r7 at the top of the loop.) Even if you disable that bit of RTL loop unrolling, you also need to disable the web pass so as to not really break the code shape for auto-inc/dec and introduce spurious moves into the RTL. Once you do that, you get: Unroll: @ Function supports interworking. @ args = 0, pretend = 0, frame = 0 @ frame_needed = 0, uses_anonymous_args = 0 @ link register save eliminated. add ip, r1, #256 .L2: ldr r2, [r1, #0] mul r3, r2, r0 str r3, [r1], #4 ldr r2, [r1, #0] mul r3, r2, r0 str r3, [r1], #4 ldr r2, [r1, #0] mul r3, r2, r0 str r3, [r1], #4 ldr r2, [r1, #0] mul r3, r2, r0 str r3, [r1], #4 ldr r2, [r1, #0] mul r3, r2, r0 str r3, [r1], #4 ldr r2, [r1, #0] mul r3, r2, r0 str r3, [r1], #4 ldr r2, [r1, #0] mul r3, r2, r0 str r3, [r1], #4 ldr r2, [r1, #0] mul r3, r2, r0 str r3, [r1], #4 cmp r1, ip bne .L2 bx lr -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36712

[Bug target/35866] Vector load/store from a packed struct does not work (without -mstrict-align)
--- Comment #4 from froydnj at gcc dot gnu dot org 2008-05-09 03:14 --- If I understand correctly, one would just need to add vector modes with appropriate alignment restrictions to SLOW_UNALIGNED_ACCESS. If I add an extra || (((MODE) == V4SFmode || (MODE) == V2DFmode) (ALIGN) 128) to SLOW_UNALIGNED_ACCESS, and compile without -mstrict-align, I get semi-reasonable looking code at -O2: f: stwu 1,-48(1) addi 9,1,16 stw 28,32(1) stw 29,36(1) stvx 2,0,9 lwz 8,12(9) lwz 5,0(9) lwz 6,4(9) mr 0,8 lwz 7,8(9) stw 8,13(3) addi 8,1,16 stw 5,1(3) stw 7,9(3) stw 6,5(3) stw 5,0(8) stw 6,4(8) stw 7,8(8) stw 0,12(8) lvx 2,0,8 lwz 28,32(1) lwz 29,36(1) addi 1,1,48 blr It could be improved, but it's a lot better than -mstrict-align code. -- froydnj at gcc dot gnu dot org changed: What|Removed |Added CC||froydnj at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35866
