From: Senthil Kumar Selvaraj Date: Wed, 23 Nov 2016 09:49:25 +0000 (+0000) Subject: Fix bogus failure of uninit-19.c for avr X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=baf53c4739a68b3307ce28bfeffc903fa641b946;p=gcc.git Fix bogus failure of uninit-19.c for avr The test fails for avr because fn1 does not get inlined into fn2. Inlining occurs for x86_64 because fn1's computed size equals call_stmt_size. For the avr, 32 bit memory moves are more expensive, and b[3] = p10[a] results in a bigger size for fn1, preventing the inlining. Add -finline-small-functions to force early inliner to inline fn1. gcc/testsuite/ 2016-11-23 Senthil Kumar Selvaraj * gcc.dg/uninit-19.c: Add -finline-small-functions for avr.
