Bug ID: 59462
Summary: c-c++-common/cilk-plus/AN/builtin_func_double2.c fails
on MIPS
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sje at gcc dot gnu.org
CC: rsandifo at gcc dot gnu.org
Target: mips*-*-*
The test c-c++-common/cilk-plus/AN/builtin_func_double2.c is failing on both of
my mips targets (mips-mti-elf and mips-mti-linux-gnu). Here is a cutdown
test case:
int foo(void)
{
int y, i;
double array[100];
for (i = 0; i < 100; i++)
{
array[i] = (double) i;
}
y = __sec_reduce_any_nonzero (array[:]);
return y;
}
And here is the failure when compiled with g++ -O2 -ftree-vectorize -fcilkplus.
For some reason the same code compiled with C instead of C++ works.
install-mips-mti-elf/bin/mips-mti-elf-g++ -c -O2 -ftree-vectorize -fcilkplus
