From 765f1bf9e4451e97ccfba21bc2d9dcee8580fb31 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Thu, 1 Apr 2004 16:45:34 +0000 Subject: [PATCH] gcc.c (init_gcc_specs): If HAVE_LD_AS_NEEDED, link with -lgcc --as-needed -lgcc_s --no-as-needed by default. * gcc.c (init_gcc_specs): If HAVE_LD_AS_NEEDED, link with -lgcc --as-needed -lgcc_s --no-as-needed by default. * configure.ac (HAVE_LD_AS_NEEDED): Check for ld --as-needed. * configure: Rebuilt. * config.in: Rebuilt. * Makefile.in (stage1-start): Copy also libgcc_s*$(SHLIB_EXT). (stage2-start, stage3-start, stage4-start): Likewise. (stageprofile-start, stagefeedback-start): Likewise.
