From b31bcacc489d6ede2e9bdfa9905de0ebfd919454 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Fri, 16 Oct 2015 03:14:40 -0700 Subject: Convert mov to lea for loading address of local common symbol There is no need to check def_regular when converting mov to lea for loading address of local symbols since def_regular may be false for common symbols and SYMBOL_REFERENCES_LOCAL is sufficient. bfd/ * elf32-i386.c (elf_i386_convert_mov_to_lea): Don't check def_regular. * elf64-x86-64.c (elf_x86_64_convert_mov_to_lea): Likewise. ld/testsuite/ * ld-i386/lea1.s: Add a test for loading address of local common symbol. * ld-x86-64/lea1.s: Likewise. * ld-i386/lea1a.d: Updated. * ld-i386/lea1b.d: Likewise. * ld-i386/lea1c.d: Likewise. * ld-x86-64/lea1a.d: Likewise. * ld-x86-64/lea1b.d: Likewise. * ld-x86-64/lea1c.d: Likewise. * ld-x86-64/lea1d.d: Likewise. * ld-x86-64/lea1e.d: Likewise. * ld-x86-64/lea1f.d: Likewise. --- ld/testsuite/ChangeLog | 15 +++++++++++++++ ld/testsuite/ld-i386/lea1.s | 3 +++ ld/testsuite/ld-i386/lea1a.d | 1 + ld/testsuite/ld-i386/lea1b.d | 1 + ld/testsuite/ld-i386/lea1c.d | 1 + ld/testsuite/ld-x86-64/lea1.s | 3 +++ ld/testsuite/ld-x86-64/lea1a.d | 1 + ld/testsuite/ld-x86-64/lea1b.d | 1 + ld/testsuite/ld-x86-64/lea1c.d | 1 + ld/testsuite/ld-x86-64/lea1d.d | 1 + ld/testsuite/ld-x86-64/lea1e.d | 1 + ld/testsuite/ld-x86-64/lea1f.d | 1 + 12 files changed, 30 insertions(+) (limited to 'ld') diff --git a/ld/testsuite/ChangeLog b/ld/testsuite/ChangeLog index af8a69f..83d28f0 100644 --- a/ld/testsuite/ChangeLog +++ b/ld/testsuite/ChangeLog @@ -1,3 +1,18 @@ +2015-10-16 H.J.
