Subject: IBM Z: Remove override of inline params
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b92e4be3a61fcdf85ea12b393716b47d6ac9477f;p=gcc.git

IBM Z: Remove override of inline params

We have pretty aggressive values for inline-min-speedup and
max-inline-insns-auto. This unfortunately made more maybe
uninitialized warnings to appear when building on Z.

With the patch we go back to the default values.

gcc/ChangeLog:

	* config/s390/s390.c (s390_option_override_internal): Remove
	override of inline params.
