2016-02-05S/390: Fix r6 vararg handling.Andreas Krebbel3-51/+111
This patch fixes a problem introduced with the GPR into FPR slot save feature for leaf functions. r6 is argument register as well as call-saved. Currently we might decide that it will be a candidate for being saved into an FPR. If it turns out later that r6 also needs to be saved due to being required for vararg we undo the FPR save decision and put it on the stack again. Unfortunately the code did not adjust the GPR restore range accordingly so that the register does not get restored in the load multiple. This fixes the following testcases on s390x: < FAIL: libgomp.c/doacross-1.c execution test < FAIL: libgomp.c/doacross-2.c execution test < FAIL: libgomp.c/doacross-3.c execution test < FAIL: libgomp.c++/doacross-1.C execution test gcc/ChangeLog: 2016-02-05 Andreas Krebbel <krebbel@linux.vnet.ibm.com> PR target/69625 * config/s390/s390.c (SAVE_SLOT_NONE, SAVE_SLOT_STACK): New defines.

2016-02-04This patch fixes an exponential issue in ccmp.c.Wilco Dijkstra4-8/+45
This patch fixes an exponential issue in ccmp.c. When deciding which ccmp expansion to use, the tree nodes gs0 and gs1 are fully expanded twice. If they contain more CCMP opportunities, their subtrees are also expanded twice. When the trees are complex the expansion takes exponential time and memory. As a workaround in GCC6 compute the cost of the first expansion early, and only try the alternative expansion if the cost is low enough. This rarely affects real code, eg. SPECINT2006 has identical codesize. 2016-02-04 Wilco Dijkstra <wdijkstr@arm.com> gcc/ PR target/69619 * ccmp.c (expand_ccmp_expr_1): Avoid evaluating gs0/gs1 twice when complex. gcc/testsuite/ PR target/69619 * gcc.dg/pr69619.c: Add new test.
