Fwd: avr-gcc (compiled from trunk) not placing objects in attributed sections in some cases.

Hi there, Not sure if this is generic to any gcc target, or it just happens for avr, given previous mentioned problems with the .data section dissappearing (due to -gc-sections) causing .bss to be resolved to the wrong addresses for avr... Anyway, this is my test case and what happens, which doe

Ada bootstrap failure

Hi Arnaud and Robert, I have not been able to bootstrap pristine gcc trunk this morning (rev. 213544) with Ada enabled. I have set up a bisecting script which has pointed to revision 213541 as the first failing one (if you use git mirror, it is git commit 54d549ff02e4549ff12977a2c3e71e163cda066a)

[AArch64] Usage of FP regs whe only GP regs are allowed

I noticed that when -mgeneral-regs-only FP registers are still used by the LRA for spilling. Though in rare cases I saw an ICE because of it, even when it works it seems to me that the compiler should follow the desires of its user. I filed PR 62014 and posted there a patch to address this issue
