* Written by Mikael Pettersson, [EMAIL PROTECTED], 2005-05-22.
* Adapted from glibc-2.3.5/sysdeps/generic/s_fmax.c
*
* gcc-3.4.4 configured for arm-unknown-linux gets an
* internal compiler error when compiling this program
* with optimisation enabled:
*
* gcc3_arm_bug.c: In function `__fmax':
* gcc3_arm_bug.c:28: internal compiler error: in elim_reg_cond, at flow.c:3267
*
* Notes:
* - gcc-3.4.4 was built as a cross-compiler for arm-unknown-linux
* hosted on i686-pc-linux-gnu. The cross-compilation toolchain
* consisted of binutils-2.16, gcc-3.4.4, glibc-2.3.5, and kernel
* headers from linux-2.4.30.
* - Using -O0 prevents the ICE.
* - gcc-3.4.4, gcc-3.3.6, and gcc-3.2.3 all exhibit this bug.
* - gcc-4.0.1 (20050521) does not have this bug.
