MI testcases currently all fail on native Windows with:
Running /c/gdb/src/gdb/testsuite/gdb.mi/mi-simplerun.exp ...
ERROR: (timeout) GDB never initialized after 10 seconds.
This is because when GDB is started in MI mode, it prints info to the
terminal before -iex options are processed. I.e., before the "maint
set console-translation-mode binary" command in
gdb -nw -nx -q -iex "set height 0" -iex "set width 0" \
-iex "set interactive-mode on" \
-iex "maint set console-translation-mode binary" \
-i=mi
... is processed. This results in GDB printing early output with
\r\r\n, like can be easily seen by passing --debug to runtest:
expect: does "=thread-group-added,id="i1"\r\r\n=cmd-param-changed,param="width",value="4294967295"\r\r\n=cmd-param-changed,param="interactive-mode",value="on"\r\r\n(gdb) \r\n" (spawn_id exp10) match regular expression "~"GNU.*\r\n~".*[(]gdb[)] \r\n$"? Gate "~"GNU*\r\n~"*gdb? \r\n"? gate=no
Fix this by adding a new Windows-only --binary-output command line
option to GDB, which is processed much earlier than -iex, and making
the testsuite pass that instead of "maint set console-translation-mode
binary".
Remove "maint set console-translation-mode" completely, since the only
reason it existed was for the testsuite, and it was never included in
any release.
