2017-11-15Use compare-debug for bootstrap-debug-lean to ignore != DW_AT_produceraoliva
Unlike bootstrap-debug, bootstrap-debug-lean used to pass compare using the traditional compare command, because it compiled both stage2 and stage3 with options that used to generate identical output (-fcompare-debug= in stage2 vs -fcompare-debug in stage3). Since we started adding relevant command-line flags to DW_AT_producer, this is no longer the case, and stages 2 and 3 object files that differ in nothing but the DW_AT_producer strings. -fcompare-debug is short for -fcompare-debug=-gtoggle, so stage3 compiles twice, once with the normal options, once with toggled -g, to then compare the temporary final dumps. When enabled, both compilations get from the driver an additional -frandom-seed flag (if none is given explicitly). -fcompare-debug= is short for -fno-compare-debug, disabling the second compilation. The difference between the DW_AT_producer lines are the different -fcompare-debug flags, and the presence of the -frandom-seed flag in the stage3 compilation. It is easy and sensible enough to filter the -fcompare-debug flags out of the DW_AT_producer string. This option should never affect the compilation output, it just determines whether or not to perform an additional compilation that should produce the same executable output. However, dropping -frandom-seed is not quite correct, in that it might have other consequences on the compilation. So, it makes little sense to make the effort to drop it when it's implicit; for those comparing compiler output differences, it might even hint at what causes, and could fix, difficult to explain differences, namely, explicitly supplying -frandom-seed options. They don't seem to matter for compiler bootstraps, though, at least for now, so we can safely refrain from issuing -frandom-seed (or maybe we already issue it where needed :-), and then, for bootstrap-debug-lean, use the compare-debug script, that strips out debug information before comparing the object files. for config/ChangeLog * bootstrap-debug-lean.mk (do-compare): Use the contrib/compare-debug script. for gcc/ChangeLog * dwarf2out.c (gen_producer_string): Discard OPT_fcompare_debug. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@254750 138bc75d-0d04-0410-961f-82ee72b054a4

2015-08-24Missing parts of fixes for in-tree libiconvpalves
(The previous iconv-related commit missed the config/iconv.m4 change.) Original description: This is the second in a series of patches to make a build with an in-tree GNU libiconv work as designed. Currently GDB is the only toolchain component which actually uses an in-tree libiconv. This patch modifies the common AM_ICONV to use an in-tree libiconv when present and not already provided by libc. (GDB's workaround uses an in-tree libiconv even when libc provides iconv(3); I'm not sure when or why that would be desirable.) config/ChangeLog: 2015-08-24 Yaakov Selkowitz <yselkowi@redhat.com> * iconv.m4 (AM_ICONV_LINK): Use in-tree libiconv when present. --- config/ChangeLog | 4 +++ config/iconv.m4 | 47 +++++++++++++++++++++------ 4 files changed, 112 insertions(+), 36 deletions(-) diff --git a/config/iconv.m4 b/config/iconv.m4 index c5f3579..5f9304a 100644 --- a/config/iconv.m4 +++ b/config/iconv.m4 @@ -7,6 +7,7 @@ dnl that contains a configuration script generated by Autoconf, under dnl the same distribution terms as the rest of that program. dnl From Bruno Haible. +dnl with modifications to support building with in-tree libiconv AC_DEFUN([AM_ICONV_LINKFLAGS_BODY], [ @@ -28,24 +29,51 @@ AC_DEFUN([AM_ICONV_LINK], dnl accordingly.
