From: Tom de Vries Date: Mon, 21 Oct 2019 13:08:54 +0000 (+0200) Subject: [gdb/testsuite] Compile infcall-nested-structs.exp with -O2 X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=94cb3754118669d46c8ad87c986d8d9c59fac65a;p=deliverable%2Fbinutils-gdb.git [gdb/testsuite] Compile infcall-nested-structs.exp with -O2 As mentioned in commit 745ff14e6e1 "[gdb/tdep] Fix 'Unexpected register class' assert in amd64_push_arguments", of the 12 KFAILs added there, 3 are KPASSing with g++ 4.8.5. The KPASSes are due to: - gdb incorrectly expecting the second half of the result of function rtn_str_struct_02_01 in register %rdx. - rtn_str_struct_02_01 using %rdx as a temporary, thereby accidentally setting it to the expected value. Reduce the chance of hiding errors due accidental register settings by compiling the test-case with -O2. This fixes the KPASSes when applied on top of commit 745ff14e6e1. Tested on x86_64-linux. Tested with g++ 4.8.5, 7.4.1, 8.3.1, 9.2.1. gdb/testsuite/ChangeLog: 2019-10-21 Tom de Vries * gdb.base/infcall-nested-structs.c: Add __attribute__((noinline,noclone)) to all functions. (call_all): Add missing variable initialization. Simplify return value. (breakpt): Increment volatile variable, to prevent call from being optimized out. * gdb.base/infcall-nested-structs.exp: Compile with -O2.
