Bug #: 53708
Summary: [4.8 Regression] Many failures of the objc tests with
-O3 -fnext-runtime and -m32
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: domi...@lps.ens.fr

Host: *-apple-darwin*
Target: *-apple-darwin*
Build: *-apple-darwin*
Between revisions 188187 (OK) and 188246 over one hundred tests failed with
-m32 and -O3 -fnext-runtime on *-apple-darwin*:

On x86_64-apple-darwin10 I also see the following failures with -m64

while on powerpc-apple-darwin9 I only see the execution failures. The
compilation failures are all of the kind
ld: in /var/tmp//ccVsf9ME.o, S_LITERAL_POINTERS section __OBJC,__message_refs
missing relocs
collect2: error: ld returned 1 exit status
They disappear if I compile the tests with '-O3 -fno-tree-vectorize', but
reappear with '-O2 -ftree-vectorize'.
According to Iain Sandoe, this is due to revisions 188235/188243.
