- Subject: ARM string optimizations broken for ARMv3
Hi,
In newlib 1.18.0 there were introduced some assembler optimizations
regarding string operations in arm.
These fail to assemble at least when?targeting?armv3 (implied by
-mcpu=arm7, which is implied by my multilib setup).
As far as I could see, the offending instructions are load/store half
words, that aren't supported (at least accordingly to gnu AS)?on this
architecture.
Is there a patch already available on cvs or something?
