Subject: S/390: Fix larl/PIC test case.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5719731f479e4aa29035cfa540a67245cfe15321;p=gcc.git

S/390: Fix larl/PIC test case.

This patch adds -march=z900 to a test case that expects larl for loading
a value via the GOT.  On z10 and later, lgrl is used which is tested in
a new, separate test case.

gcc/testsuite/ChangeLog:

2019-05-17  Robin Dapp  <rdapp@linux.ibm.com>

  * gcc.target/s390/global-array-element-pic.c: Add -march=z900.
  * gcc.target/s390/global-array-element-pic2.c: New test for z10+.
