Description Eric Botcazou 2003-05-31 07:06:27 UTC
GCC 3.3 emits out of range loop instructions for FP code when optimizing for the
K6 family of processors.

sv_main.s: Assembler messages:
sv_main.s:2753: Error: value of -134 too large for field of 1 bytes at 7337

The testcase assembles fine when compiled with GCC 3.2.3 (but this may be purely
by luck) so I marked it as a regression.
