sandra at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sandra at gcc dot gnu.org --- Comment #1 from sandra at gcc dot gnu.org --- I'm seeing most of these on nios2-elf as well. Including <alloca.h> doesn't fix the malloc-callbacks.c failures on this and other newlib targets; newlib's version of that header file defines alloca as a function-like macro instead of a function. Also observed on nios2-elf: FAIL: gcc.dg/analyzer/pattern-test-2.c <unknown> == 0 (test for warnings, line 21) FAIL: gcc.dg/analyzer/pattern-test-2.c <unknown> != 0 (test for warnings, line 21) FAIL: gcc.dg/analyzer/pattern-test-2.c (test for excess errors) Excess errors: /path/to/gcc/testsuite/gcc.dg/analyzer/pattern-test-2.c:21:6: warning: pattern match on 'p == 0' /path/to/gcc/testsuite/gcc.dg/analyzer/pattern-test-2.c:21:17: warning: pattern match on 'q == 0'
