From 02e0be69012aee9aac0c7adbba1b0516b4dc9218 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Wed, 5 Feb 2020 16:19:17 +1030 Subject: [PATCH] mbind gas tests and supports_gnu_osabi testsuite infrastructure With the addition of section16 tests we have multiple tests advertising themselves as "mbind sections" and "mbind section contents". This patch fixes that, and fails on quite a few targets that force an OSABI value. It's a pain specifying all the relevant arm targets on an xfail line, so I wrote supports_gnu_osabi. binutils/ * testsuite/lib/binutils-common.exp (match_target): Accept '!' before TCL procedure. (supports_gnu_osabi): New procedure. (is_generic): New, from ld-lib.exp. (supports_gnu_unique): Use the above. gas/ * testsuite/gas/elf/section12a.d: Use supports_gnu_osabi in xfail, and rename test. * testsuite/gas/elf/section12b.d: Likewise. * testsuite/gas/elf/section16a.d: Likewise. * testsuite/gas/elf/section16b.d: Likewise. ld/ * testsuite/lib/ld-lib.exp (is_generic): Delete. * testsuite/ld-unique/unique.exp: Exclude tic6x. --- binutils/ChangeLog | 8 +++ binutils/testsuite/lib/binutils-common.exp | 59 +++++++++++++++------- gas/ChangeLog | 8 +++ gas/testsuite/gas/elf/section12a.d | 5 +- gas/testsuite/gas/elf/section12b.d | 5 +- gas/testsuite/gas/elf/section16a.d | 5 +- gas/testsuite/gas/elf/section16b.d | 5 +- ld/ChangeLog | 5 ++ ld/testsuite/ld-unique/unique.exp | 2 +- ld/testsuite/lib/ld-lib.exp | 12 ----- 10 files changed, 71 insertions(+), 43 deletions(-) diff --git a/binutils/ChangeLog b/binutils/ChangeLog index 6214de979e..7dc97dbd85 100644 --- a/binutils/ChangeLog +++ b/binutils/ChangeLog @@ -1,3 +1,11 @@ +2020-02-06 Alan Modra + + * testsuite/lib/binutils-common.exp (match_target): Accept '!' before + TCL procedure. + (supports_gnu_osabi): New procedure. + (is_generic): New, from ld-lib.exp. + (supports_gnu_unique): Use the above. + 2020-02-04 Alan Modra * Makefile.am (CFILES): Add od-elf32_avr.c. diff --git a/binutils/testsuite/lib/binutils-common.exp b/binutils/testsuite/lib/binutils-common.exp index a253c01a5c..57b94f528a 100644 --- a/binutils/testsuite/lib/binutils-common.exp +++ b/binutils/testsuite/lib/binutils-common.exp @@ -171,32 +171,38 @@ proc is_rela { binary_file } { # in square brackets or as machine triplet otherwise. # proc match_target { target } { - if [string match {\[*\]} $target] { + if [regexp {^!?\[.*\]$} $target] { return $target } else { return [istarget $target] } } -# True if the ELF target supports STB_GNU_UNIQUE with the ELF header's -# OSABI field set to ELFOSABI_GNU. +# True if the ELF target supports setting the ELF header OSABI field +# to ELFOSABI_GNU or ELFOSABI_FREEBSD, a requirement for STT_GNU_IFUNC +# symbol and SHF_GNU_MBIND section support. # # This generally depends on the target OS only, however there are a # number of exceptions for bare metal targets as follows.
