Should I file this as a bug? -------------------------------------------------------------- The output of `arm-none-eabi-g++ -v` is : Using built-in specs. See for instructions. -------------------------------------------- The expected behaviour is that such code should compile fine. On 4.7 is doesn't have a reg at all, ie. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=44787

Comment 2 Chung-Lin Tang 2011-04-12 04:43:01 UTC Author: cltang Date: Tue Apr 12 04:42:55 2011 New Revision: 172297 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=172297 Log: 2011-04-11 Chung-Lin Tang Richard Earnshaw PR target/48250 * The problem is that reload uses the mem for the pseudo without any concern for insn constraints. (Well, not entirely, but gen_reload in this case just uses gen_move_insn.) This in turn So, why don't we simply use "m" in movdi_internal32 in place of "o<>"?

On mainline we come out of the reload loop with the pseudo being assigned a gpr. I don't think this is the same bug as PR42949 because that one has now ceased to occur - for me at least.

I tried revision 160946 and did not see such error. Ah, no, that patch was for find_moveable_pseudos which we don't have on 4.7. It can and should generate stw 6,32760(19); stw 7,32764(19). 2) The failing constraint is "o<>", specifically "o" so offsettable_memref_p is involved. http://colvertgroup.com/internal-compiler/internal-compiler-error-net.php to the correct ones to reproduce): /cygdrive/d/sdk/android-ndk/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/arm-linux-androideabi-g++ -fpic -ffunction-sections -funwind-tables -fstack-protector -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__ -Wno-psabi -march=armv7-a -mfloat-abi=softfp -mfpu=vfp -fno-exceptions -fno-rtti -O2 -fomit-frame-pointer -fstrict-aliasing -funswitch-loops -finline-limit=300 -mfpu=neon -DANDROID -gstabs+ -Wa,--noexecstack -frtti

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).

comment:2 Changed 2 years ago by Gedare Description modified (diff) Milestone changed from 2 to 4.9 Version changed from unknown to 4.8 Note: See TracTickets for help on using tickets. Is this something we have to worry about ? Backport r171632 from mainline 2011-03-28 Richard Sandiford * builtins.c (expand_builtin_memset_args): Use gen_int_mode instead of GEN_INT. Note You need to log in before you can comment on or make changes to this bug.

What's wrong with using "m" instead of "o<>"? Seems this works because + 32764 is not rs6000_legitimate_offset_address_p. I have cut the file target.c down to the minium that seems to trigger the bug.

Other register address like: fp, lr or sp are instead always working fine. Comment 4 Jakub Jelinek 2012-07-09 04:13:47 EDT I wonder if we shouldn't use in movdi_internal32 simply a predicate that for MEM checked offsettable_mem_operand (or of course, change mode_dependent_address hook to include Download in other formats: Comma-delimited Text Tab-delimited Text RSS Feed Powered by Trac 1.0.3dev-r0 By Edgewall Software.
