[-- Attachment #1: Type: text/plain, Size: 1205 bytes --]
By default, wildcard support on Windows for programs compiled with mingw depends
on how the mingw runtime was configured. This means if one wants to build GCC
for Windows with a consistent behavior with Wildcard (enabled or disabled) the
mingw runtime must be built as well. This patch adds an option to GCC
configuration to force the behavior with wildcard when building GCC for Windows
host. It does so by setting the _dowildcard variable in the driver to a given
value depending on the configure option value (yes or no), thus overriding the
variable from mingw runtime.
Testing: I've successfully done a build of the arm-none-eabi cross GCC for
Windows with Ubuntu system mingw runtime (configured without wildcard support by
default) with the three configure options:
1) --enable-wildcard: wildcard can be used successfully and nm of
driver-mingw32.o shows that _dowildcard is in .data section
2) --disable-wildcard: wildcard cannot be used and nm of driver-mingw32.o
shows that _dowildcard is in .bss section
3) no option: wildcard cannot be used and nm of driver-mingw32.o shows no
_dowildcard defined and all sections are empty
Is this ok for stage1?
Best regards,
Thomas

No objections, but documentation should mention that wildcard expansion
is not handled by the CMD shell on Windows, it is up to individual
programs to interpret it.

Do you mean that this configuration option should make it clear that it only
affects wildcard expansion for GCC itself but not for programs built by GCC?

Thomas

How about the attached updated patch? Here's the associated ChangeLog entry:
2017-01-24 Thomas Preud'homme <thomas.preudhomme@arm.com>
* configure.ac (--enable-mingw-wildcard): Add new configurable feature.
* configure: Regenerate.
* config.in: Regenerate.
* config/i386/driver-mingw32.c: new file.
* config/i386/x-mingw32: Add rule to build driver-mingw32.o.
* config.host: Link driver-mingw32.o on MinGW host.
* doc/install.texi: Document new --enable-mingw-wildcard configure
option.
Best regards,
Thomas

Looks good, be sure to emphasize this option affects mingw hosted GCC

I think that should be pretty clear in the latest version of the patch,
doc/install.texi contains:
"Note that this option only affects wildcard expansion for GCC itself. It does
not affect wildcard expansion of executables built by the resulting GCC."
If you think a part of that sentence is still confusing please let me know and
I'll improve it.
Best regards,
Thomas

Hi,
We've decided to apply the following patch to the ARM/embedded-7-branch as we
did earlier for the ARM/embedded-6-branch. Patch attached for reference.
Best regards,
