From f7990f1690e9ef0471634c871c790f6cf706866d Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Wed, 9 Mar 2016 15:52:43 +0000 Subject: [PATCH] Avoid spaces in osabi names It's not possible today to select some of the osabis by name. Specifically, those that have spaces in their names and then the first word is ambiguous... For example: (gdb) set osabi [...] FreeBSD ELF FreeBSD a.out [...] (gdb) set osabi FreeBSD ELF Ambiguous item "FreeBSD ELF". In reality, because "set osabi" is an enum command, that was equivalent to trying "set osabi FreeBSD", which is then obviously ambiguous, because of "FreeBSD ELF" and "FreeBSD a.out". Also, even if the first word is not ambiguous, we actually ignore whatever comes after the first word: (gdb) set osabi GNU/Linux (gdb) show osabi The current OS ABI is "GNU/Linux". The default OS ABI is "GNU/Linux". (gdb) set osabi Windows SomeNonsense ^^^^^^^^^^^^ (gdb) show osabi The current OS ABI is "Windows CE". The default OS ABI is "GNU/Linux". (gdb) Fix this by avoiding spaces in osabi names. We could instead make "set osabi" have a custom set hook, or alternatively make the enum set hook (in cli-setshow.c) handle values with spaces, but OTOH, I have a feeling that could cause trouble. E.g., in cases where we might want to write more than one enum value in the same line. We could support quoting as workaround, but, not sure we want that. "No spaces" seems like a simpler rule. gdb/ChangeLog: 2016-03-09 Pedro Alves * osabi.c (gdb_osabi_names): Avoid spaces in osabi names. --- gdb/ChangeLog | 4 ++++ gdb/osabi.c | 18 +++++++++--------- 2 files changed, 13 insertions(+), 9 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 56bcc67..0840a51 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,9 @@ 2016-03-09 Pedro Alves + * osabi.c (gdb_osabi_names): Avoid spaces in osabi names. + +2016-03-09 Pedro Alves + * frv-tdep.c (frv_gdbarch_init): Handle bfd_mach_fr300. 2016-03-09 Pedro Alves diff --git a/gdb/osabi.c b/gdb/osabi.c index e8a77ab..f7d4e74 100644 --- a/gdb/osabi.c +++ b/gdb/osabi.c @@ -64,17 +64,17 @@ static const struct osabi_names gdb_osabi_names[] = { "GNU/Hurd", NULL }, { "Solaris", NULL }, { "GNU/Linux", "linux(-gnu)?" }, - { "FreeBSD a.out", NULL }, - { "FreeBSD ELF", NULL }, - { "NetBSD a.out", NULL }, - { "NetBSD ELF", NULL }, - { "OpenBSD ELF", NULL }, - { "Windows CE", NULL }, + { "FreeBSD/a.out", NULL }, + { "FreeBSD/ELF", NULL }, + { "NetBSD/a.out", NULL }, + { "NetBSD/ELF", NULL }, + { "OpenBSD/ELF", NULL }, + { "WindowsCE", NULL }, { "DJGPP", NULL }, { "Irix", NULL }, - { "HP/UX ELF", NULL }, - { "HP/UX SOM", NULL }, - { "QNX Neutrino", NULL }, + { "HP-UX/ELF", NULL }, + { "HP-UX/SOM", NULL }, + { "QNX-Neutrino", NULL }, { "Cygwin", NULL }, { "AIX", NULL }, { "DICOS", NULL }, -- 2.7.4
