S/390: Add support for section anchors
gcc/ChangeLog:
2018-12-03 Ilya Leoshkevich <iii@linux.ibm.com>
* common/config/s390/s390-common.c (s390_option_init_struct):
Use section anchors by default.
* config/s390/s390.c (s390_check_symref_alignment): Handle
anchors.
(TARGET_MAX_ANCHOR_OFFSET): Use short displacement.
* output.h (assemble_align): Pass `align' as unsigned int, so
that the value 0x80000000, which corresponds to `aligned(1 <<
28)', would pass the `align > BITS_PER_UNIT' check.
* varasm.c (assemble_align): Likewise.
gcc/testsuite/ChangeLog:
2018-12-03 Ilya Leoshkevich <iii@linux.ibm.com>
* gcc.target/s390/nodatarel-1.c: Expect .LANCHOR0@GOTENT instead
of a@GOTENT.
* gcc.target/s390/section-anchors.c: New test.
* gcc.target/s390/section-anchors2.c: New test.
* gcc.target/s390/section-anchors3.c: New test.
