Description:   Last confirmed: Opened: 2002-05-24 05:26
	gcc -O2 takes forever on some parsers generated by a test
	version of Bison.

Release:
3.1

Environment:
Solaris 8 (sparc)
System: SunOS sic.twinsun.com 5.8 Generic_108528-14 sun4u sparc SUNW,UltraSPARC-IIi-Engine
Architecture: sun4

	
host: sparc-sun-solaris2.8
build: sparc-sun-solaris2.8
target: sparc-sun-solaris2.8
configured with: ../gcc-3.1/configure --disable-nls --enable-languages=c,c++,f77 --prefix=/opt/reb --with-local-prefix=/opt/reb --with-system-zlib : (reconfigured) ../gcc-3.1/configure --disable-nls --enable-languages=c,c++,f77 --prefix=/opt/reb --with-local-prefix=/opt/reb --with-system-zlib

How-To-Repeat:
Compile the following program with 'gcc -O2 input.c'.  I gave
up after 10 minutes of CPU time.  Without -O2, it compiles in
7 seconds.

I moved the code into an attachment

 The test case is in the "How-To-Repeat" section of that bug report.
 However, I'll attach the test case to this message, in a slightly
 different format as a file "input.i", to make it easier for you to
 reproduce it.  To reproduce the bug, type "gcc -O2 -S input.i",
 using GCC 3.1 on Solaris 8, sparc.
