[avr-gcc-list] GCC 4.3.0 release, a few of bugs


Hi.

GCC 4.3.0 is available to download.

A few of new bugs are open at gcc-bugzilla:

New: 4.3.0 buid error: illegal opcode movw for mcu avr3
New: 4.3.0: size of small funcion increases from 2 to 29 words
New: 4.3.0: undefined reference to `__ffshi2'
New: 4.3.0: builtin isinf() mismatch to compile-time substitut

For #35506 there is a workaround: add '-mall-opcodes' option to
avr35 evaluation in ASM_SPEC.

Dmitry.

This is a duplicate of #35073. Marked as such.

Or use latest binutils HEAD, IIRC. This means that GCC >= 4.2.3, must
use binutils 2.19 (which is unreleased).

Thanks for the reports, Dmitry! I've added them to the list.
