Subject: ipa-inline: Adjust condition for caller_growth_limits
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6ac22177a085e0ba36c95e71cee8235cc8b12947;p=gcc.git

ipa-inline: Adjust condition for caller_growth_limits

Inline should return failure either (newsize > param_large_function_insns)
OR (newsize > limit).  Sometimes newsize is larger than
param_large_function_insns, but smaller than limit, inline doesn't return
failure even if the new function is a large function.
Therefore, param_large_function_insns and param_large_function_growth should be
OR instead of AND, otherwise --param large-function-growth won't
work correctly with --param large-function-insns.

gcc/ChangeLog:

	2020-01-07  Luo Xiong Hu  <luoxhu@linux.ibm.com>

	* ipa-inline-analysis.c (estimate_growth): Fix typo.
	* ipa-inline.c (caller_growth_limits): Use OR instead of AND.
