From: Gary Benson Date: Tue, 10 Nov 2020 16:40:40 +0000 (+0000) Subject: Prevent false passes in gdb.base/vla-optimized-out.exp X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=83100a74a542bc2fa99387f518712ec0ef408a4b;p=binutils-gdb.git Prevent false passes in gdb.base/vla-optimized-out.exp The "vla_optimized_out" procedure in gdb.base/vla-optimized-out.exp accepts a "sizeof_result" argument which is substituted into the regular expression used to check the result of printing the sizeof a VLA. The -O3 test variants, however, pass a regular expression fragment as that argument, which expands into a regular expression that matches any result with a "6" in it. This commit wraps the substitution with parentheses to prevent these false matches. gdb/testsuite/ChangeLog: * gdb.base/vla-optimized-out.exp (p sizeof (a)): Wrap supplied regexp fragment in parentheses to prevent false matching. --- diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 146fa1a086f..608e48d8603 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,8 @@ +2020-11-10 Gary Benson + + * gdb.base/vla-optimized-out.exp (p sizeof (a)): Wrap supplied + regexp fragment in parentheses to prevent false matching. + 2020-11-10 Gary Benson * gdb.base/vla-optimized-out.c (f1): Add __attribute__ ((weak)). diff --git a/gdb/testsuite/gdb.base/vla-optimized-out.exp b/gdb/testsuite/gdb.base/vla-optimized-out.exp index 66d1a131d95..203a82d06e3 100644 --- a/gdb/testsuite/gdb.base/vla-optimized-out.exp +++ b/gdb/testsuite/gdb.base/vla-optimized-out.exp @@ -42,7 +42,7 @@ proc vla_optimized_out {exe_suffix options} { "printed optimized out vla" gdb_test "p sizeof (a)" \ - " = $sizeof_result" \ + " = ($sizeof_result)" \ "printed size of optimized out vla" # At lower optimisation levels, the upper bound of the array is
