- Subject: disable GAS overflow check for Xtensa
- Organization: Tensilica, Inc.
I have applied this patch to fix a fairly obscure problem in the Xtensa port of
GAS that only seems to occur when assembling a really large section of code.
The patch disables the generic overflow checking, which isn't needed anyway
because the Xtensa code does its own overflow checks.

* config/tc-xtensa.c (xg_add_opcode_fix): Set fx_no_overflow.
