Bug ID: 103804
Summary: ICE: 'global_options' are modified in local context
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: ice-on-invalid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: asolokha at gmx dot com
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Target: powerpc-*-linux-gnu
gcc, at least configured for powerpc target and invoked w/ -mcpu= set to a
value valid to that target, ICEs when compiling testcases w/ explicitly wrong
(non-powerpc)
#pragrma GCC target ("")
statements and
__attribute__ ((optimize ()))
set on a function.
The following testcase was extracted from
gcc/testsuite/gcc.target/aarch64/vect-widen-add.c:
#pragma GCC target "+nosve"
#define ARR_SIZE 1024
__attribute__((optimize (0))) void
uadd_nonopt (unsigned int *foo, unsigned short int *a, unsigned short int *b)
{
for( int i = 0; i < ARR_SIZE - 3;i=i+4)
{
foo[i] = a[i] + b[i];
foo[i+1] = a[i+1] + b[i+1];
foo[i+2] = a[i+2] + b[i+2];
foo[i+3] = a[i+3] + b[i+3];
}
}
