gcc48-pr54796.patch
Untested patch that looks promissing to me.
For -m32 guality.exp results improve:
+XPASS: gcc.dg/guality/example.c -Os execution test
-FAIL: gcc.dg/guality/pr43051-1.c -Os line 39 c == &a[0]
-FAIL: gcc.dg/guality/pr54519-3.c -Os line 23 y == 117
-FAIL: gcc.dg/guality/pr54519-3.c -Os line 23 z == 8
(plus all gcc.dg/guality/pr54796.c -O1 and above results which fail without the
non-testsuite part of the patch). For -m64 no change (expectedly, one would
need to have more than 6 arguments in teststo trigger stack slot passing).
