* [Bug c/37763] New: bad interaction of -O3 -pg and -mcu=arm920t ?? @ 2008-10-07 17:24 steven dot paul at monotypeimaging dot com 2008-10-07 20:37 ` [Bug target/37763] " pinskia at gcc dot gnu dot org ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: steven dot paul at monotypeimaging dot com @ 2008-10-07 17:24 UTC (permalink / raw) To: gcc-bugs Are there known issues among the -pg and -O3 and -mcu=arm9020t options ? I am using Gcc 3.3.5 on Debian 1:3.3.5-13, running on a Technologic systems TS-7200 board with an Arm920T processor. Compiling a medium size program (~ 1.5mb source code) with flags -O3 -mcu=arm920t -Wall I get no errors/warnings, and the program runs to completion w/o error Yet compiling with the flags -O3 -pg -mcu=arm920t -Wall produces no errors/warnings, butproduces Segment errors at runtime -- the location of the error varies; which is unusual as the program is deterministic. And compiling with the flags -O3 -g -mcu=arm920t -Wall produces no errors/warnings, and runs to completion (either at command line or inside gdb) w/o error. fiy ... compiling the program with these sets of flags -mcu-arm920t -Wall and -03 -mcu=arm920t -Wall compile with no errors/warnings, run to completion w/o error, and and produces identical large (~2gB) regression test output. If there are no known issues among these flags, I'll work to get a smaller code base which will reproduce the bug. thanks... -- Summary: bad interaction of -O3 -pg and -mcu=arm920t ??

Also the ARM back-end has been improved and there has been a big ABI change (over to a standard ABI). We also need the preprocessed source where the issue is. -- pinskia at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Component|c |target GCC target triplet| |arm-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37763 ^ permalink raw reply [flat|nested] 5+ messages in thread
