Bug ID: 77710
Summary: FAIL: gcc.dg/tree-ssa/builtin-sprintf-warn-4.c
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: thopre01 at gcc dot gnu.org
CC: msebor at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux-gnu
Target: arm-none-eabi
Hi,
gcc.dg/tree-ssa/builtin-sprintf-warn-4.c fails on arm-none-eabi targets for
excess errors because it does not seem to see the dg-warning and dg-message
directive. This seems to be related to the multiline checks because when
removing those the warnings are catched.
Here is the output I get:
