From: Jakub Jelinek Date: Wed, 25 Mar 2020 10:41:17 +0000 (+0100) Subject: testsuite: Mention cleanup-13.c test is incompatible with -fcompare-debug [PR94296] X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=780f1cfd8eef90f6f5ea84cf58aa97e07c0c2aa1;p=gcc.git testsuite: Mention cleanup-13.c test is incompatible with -fcompare-debug [PR94296] As this test produces different code depending on whether __GCC_HAVE_DWARF2_CFI_ASM macro is defined or not, it is inherently incompatible with -fcompare-debug, as with -fcompare-debug -fno-asynchronous-unwind-tables -fno-exceptions the macro is defined only in the -g case and not otherwise. The purpose of the macro is to tell when the compiler is emitting .cfi* directives itself and thus it is desirable that user code uses them in inline asm as well, so I think it is fine the way it is. As -fexceptions makes the test pass even in that case because it emits .cfi* directives, the test actually doesn't FAIL even with make check-gcc RUNTESTFLAGS='--target_board=unix/-fcompare-debug/-fno-asynchronous-unwind-tables/-fno-exceptions dg.exp=cleanup-13.c' so the intent of this patch is help Martin and others who do run gcc tests out of the testsuite with random compiler flags to find out that this is a known issue. 2020-03-25 Jakub Jelinek PR debug/94296 * gcc.dg/cleanup-13.c: Add a comment that the test is not -fcompare-debug compatible with certain other options. --- diff --git a/gcc/testsuite/ChangeLog b/gcc/testsuite/ChangeLog index 5196036f64a..86d3b719ab8 100644 --- a/gcc/testsuite/ChangeLog +++ b/gcc/testsuite/ChangeLog @@ -1,5 +1,9 @@ 2020-03-25 Jakub Jelinek + PR debug/94296 + * gcc.dg/cleanup-13.c: Add a comment that the test is not + -fcompare-debug compatible with certain other options. + PR target/94308 * gcc.target/i386/pr94308.c: New test. diff --git a/gcc/testsuite/gcc.dg/cleanup-13.c b/gcc/testsuite/gcc.dg/cleanup-13.c index 1b7ea5c4b28..86cfae09e77 100644 --- a/gcc/testsuite/gcc.dg/cleanup-13.c +++ b/gcc/testsuite/gcc.dg/cleanup-13.c @@ -1,3 +1,7 @@ +/* This test is expected to FAIL to compile with + -fcompare-debug -fno-asynchronous-unwind-tables -fno-exceptions + because in that case, the __GCC_HAVE_DWARF2_CFI_ASM macro is only + defined during -g compilation and not defined with -g0. */ /* HP-UX libunwind.so doesn't provide _UA_END_OF_STACK */ /* { dg-do run } */ /* { dg-options "-fexceptions" } */
