Bug ID: 81638
Summary: AIX bootstrap failure due to Recover GOTO predictor
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: dje at gcc dot gnu.org
Target Milestone: ---
Target: powerpc-ibm-aix*
The patch breaks bootstrap on AIX and probably is a hidden bug on all targets.
With the patch, libbacktrace/xcoff.c fails to compile with the error:
/nasfarm/edelsohn/src/src/libbacktrace/xcoff.c: In function 'xcoff_add':
/nasfarm/edelsohn/src/src/libbacktrace/xcoff.c:822:13: error: 'incl'
may be used uninitialized in this function
[-Werror=maybe-uninitialized]
filename = incl->filename;
~~~~~~~~~^~~~~~~~~~~~~~~~
/nasfarm/edelsohn/src/src/libbacktrace/xcoff.c:777:22: note: 'incl'
was declared here
struct xcoff_incl *incl;
^~~~
incl is used immediately above the line that produces the warning --
with no warning.
