Bug ID: 71124
Summary: Compiler enters infinite loop on Microblaze with
-O1/-O2/-O3
Product: gcc
Version: 4.9.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target

Test case
The attached preprocessed C++ file (generated from the assimp project) causes
g++ 4.9.3 to enter an infinite loop if an optimization level of -O1, -O2 or -O3
is used. With no optimization flags, or with the -Os flag, the compiler works
fine.
I.e:
microblazeel-linux-g++ -O1 -c test.cpp
microblazeel-linux-g++ -O2 -c test.cpp
microblazeel-linux-g++ -O3 -c test.cpp
never terminate.
While:
microblazeel-linux-g++ -c test.cpp
microblazeel-linux-g++ -Os -c test.cpp
terminate properly.
