Internal Compiler Error In Reload_cse_simplify_operands At Postreload.c

Comment 10 Alan Modra 2012-07-16 23:49:13 EDT What's happening here is that the pseudo for the reg in insn 1485 doesn't get a hard reg. There are two other bugs in flight that manifest in reload_cse_simplify_operands: PR48250 (broke on trunk for EABI, works on 4.5 for EABI) and PR42949 (works on EABI for trunk and gcc4.5, Backport r171379 from mainline 2011-03-23 Chung-Lin Tang PR target/46934 * config/arm/arm.md (casesi): Use the gen_int_mode() function to subtract lower bound instead of GEN_INT().

Using a trunk (svn 171251) compiler, configured for ARMv7-a, I get the following ICE: gcc -marm -mfpu=neon -O2 -c lp723185.i lp723185.i: In function 'foo': lp723185.i:29:1: error: insn does not satisfy its ppc-koji build --scratch f18 gcc-4.7.1-1.fc18.src.rpm 2. 3. Comment 12 Jakub Jelinek 2012-07-17 05:13:19 EDT For the time being I've applied the small change on *movdi_internal32 from "=o<>,..." to "=m,..." in the constraint (the change is in gcc-4.7.1-3.fc18).

Note: This is an automated response to your message "[Bug 723185]" sent on 12/4/2011 7:43:01. I can't see any later constraint pairs that would match the non-offsettable parts of "m". http://gcc.gnu.org/ml/gcc-patches/2004-08/msg00022.html Geoff patched four insns, one of which, movtf_internal, has since had "o<>" replaced with "Y". Please reproduce with a vanilla FSF GCC, or report the problem to CodeSourcery as their compiler clearly directs you to do (see the --with-bugurl= setting).
