Bug ID: 22711
Summary: [powerpc64] Section .toc is not properly aligned
Product: libraries
Version: 3.6
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Backend: PowerPC
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
powerpc64 elf: section ".toc" is not properly aligned.
Interestingly it works (by accident?) when using "-save-temps".
$ cat test.c
void test(int *a) {
switch (*a++) {
case 17: *a = 2; break;
case 13: *a = 3; break;
case 11: *a = 5; break;
case 7: *a = 7; break;
case 5: *a = 11; break;
case 3: *a = 13; break;
case 2: *a = 17; break;
}
}
// EOF
$ clang-3.6.0rc4 -target powerpc64-linux-gnu -Wall -W -c test.c
$ readelf --wide -S test.o | grep ' \.toc '
[ 9] .toc PROGBITS 0000000000000000 000198 000008 00 WA

##### now using "-save-temps":
$ clang-3.6.0rc4 -target powerpc64-linux-gnu -Wall -W -save-temps -c test.c
$ readelf --wide -S test.o | grep ' \.toc '
[ 9] .toc PROGBITS 0000000000000000 000198 000008 00 WA
