2019-06-23[Darwin, PPC, testsuite] Fix builtins-1 testcase for Darwin.Iain Sandoe2-4/+9
This needs to account for Darwin's __USER_LABEL_PREFIX__. 2019-06-23 Iain Sandoe <iain@sandoe.co.uk> * gcc.target/powerpc/builtins-1.c: Account for Darwin's use of __USER_LABEL_PREFIX__. From-SVN: r272604
2019-06-23[Darwin, PPC] Handle GCC target pragma.Iain Sandoe2-0/+5
For compatibility with other members of the port. Note, that we do not handle the longcall attribute, since longcall is not required/used on current Darwin. 2019-06-23 Iain Sandoe <iain@sandoe.co.uk> * config/rs6000/darwin.h: Handle GCC target pragma. From-SVN: r272603

2019-06-23[Darwin, PPC, testsuite] Fix pr71785 testcase for Darwin.Iain Sandoe2-1/+12
Firstly, we adjust the test conditions to use non-PIC code for Darwin. Secondly, we have to account for out-of-line GPR restores which gives a false positive on one of the scan-assembler-not. Lastly, we make the test a bit more specific for Darwin - that it looks for absence of branches to local labels. 2019-06-23 Iain Sandoe <iain@sandoe.co.uk> * gcc.target/powerpc/pr71785.c: For Darwin, make test non-PIC, expect the out-of-line GPR restore, and test specifically for absence of branches to local labels.
