I can reproduce this error message with gcc-4.8 (patched by OpenEmbedded) on an

ARM platform with a simple





extern void bar();

void __attribute__((__naked__)) foo(void)

{

bar();

}





$ arm-linux-gnueabi-gcc -O2 -c /tmp/xxx.c 

/tmp/xxx.c: In function 'foo':

/tmp/xxx.c:5:1: internal compiler error: in advance_target_bb, at

sched-rgn.c:3552

Classification: Unclassified

   Product: gcc

   Version: unknown

Status: UNCONFIRMED

  Severity: normal

Full build log



When building gcc-4.8 (patched by OpenEmbedded) with '-j 8', the build fails

from time to time because bconfig.h can not be found.  A subsequent make

succeeds in these cases.

[Bug c/45817] New: __aeabi_uidiv broken when built with -Os (5/3 == 3)

   Summary: __aeabi_uidiv broken when built with -Os  (5/3 == 3)
   Product: gcc
   Version: 4.5.2
Status: UNCONFIRMED
  Severity: critical
  Priority: P3
 Component: c
AssignedTo: unassig...@gcc.gnu.org

int main(int argc, char *argv[])
{
unsigned int volatilea = 5;
unsigned int volatileb = 3;
__asm__ __volatile__("" ::: "memory");
return a/b;
}

$ arm-linux-gnueabi-gcc -O0 m.c

# /a.out ; echo $?
3


Implementation of uidiv in gcc/config/arm/lib1funcs.asm differs depending on
the -Os flag (which is used by me) and issue might be missed by regression
tests which were run with non -Os compilers.
