From 4d9aa1551545dd5365d35a0844d3b7a5a35d02f3 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Tue, 12 Mar 2013 22:46:19 +0000 Subject: * powerpc.cc (is_branch_reloc): Forward declare. (Target_powerpc::do_can_check_for_function_pointers): New predicate. (Target_powerpc::Scan::local_reloc_may_be_function_pointer): Return false for 64-bit, true for 32-bit non-branch relocs. (Target_powerpc::Scan::global_reloc_may_be_function_pointer): Likewise. * testsuite/Makefile.am (icf_test): Use linker map file instead of nm output. (icf_safe_test): Generate linker map file as well as nm output. (icf_safe_so_test): Likewise. * testsuite/Makefile.in: Regenerate. * testsuite/icf_test.sh: Parse linker map file to determine section folding. * testsuite/icf_safe_test.sh: Likewise. Expect folding for PowerPC. * testsuite/icf_safe_so_test.sh: Likewise. (X86_32_or_ARM_specific_safe_fold): Merge into.. (arch_specific_safe_fold): ..this. (X86_64_specific_safe_fold): Delete unused function. --- gold/testsuite/Makefile.am | 56 +++++++++++++++++++++++++------------- gold/testsuite/Makefile.in | 43 ++++++++++++++++++-----------
