20c2c024c1
This patch fixes an issues with six test suite expect files that do not run correctly when the test suite is not built in the source directory. The issue is these tests are not using the current "standard_testfile" call but rather using the older set command to initialize the "testfile", "srcfile" and "binprefix" variables or are missing the set for the "binprefix" variable. ----------------------------------------------- gdb/testsuite/ChangeLog 2016-08-19 Carl Love <cel@us.ibm.com> * gdb.arch/altivec-regs.exp: Use standard_testfile instead of maintaining separate logic for constructing the output path. * gdb.arch/powerpc-d128-regs.exp: Likewise. * gdb.arch/ppc-dfp.exp: Likewise. * gdb.arch/ppc-fp.exp: Likewise. * gdb.arch/vsx-regs.exp: Likewise. * gdb.arch/altivec-abi.exp: Likewise, plus added local variable binprefix for generating the additional binary files.
