Could someone send the preprocessed source for mpegaudiodec.c?
The problem might have been introduced by this change:

* pa.md: Create separate 32 and 64-bit move patterns for SI, DI, SF
and DF modes. Add alternatives to copy between general and floating
point registers to the 32-bit patterns.
* pa-64.h (SECONDARY_MEMORY_NEEDED_RTX): Delete undefine.
* pa.h (SECONDARY_MEMORY_NEEDED_RTX): Delete define.
(SECONDARY_MEMORY_NEEDED): Secondary memory is only needed when
generating 64-bit code.
* pa.c (output_move_double): Handle copies between general and
floating registers.
I need to understand if we need to support HImode and QImode moves between
the general and floating point registers. You can't do anything with an
QImode or HImode value in a floating-point register, so it's not obvious
why this is needed.
