Redirect 'Slash' NIL 113679ff59 corrective fix for MinGW GNU C99 printf compliance
Compilation on cygwin, using gcc v3 with option -mno-cygwin,
currently produces a large number of the following warnings:

   warning: `gnu_printf' is an unrecognized format function type

These have been introduced with the recent MinGW GNU C99 printf
compliance patch, as gnu_printf was only introduced with gcc v4.4
and is not recognized with earlier versions.

The attached fix adds gcc version detection to the previous patch
to avoid the problem.

Redirect 'Slash' NIL 73349dc5ac More MinGW C99 printf compliance
Passing "--std=gun99" is unfortunately not sufficient to make current
MinGW compilers conform with respect to checking printf format strings.
(The C runtime seems not to have problems.)

Fix by using a "gnu_printf" format specifier not "printf".

Redirect \"Slash\" NIL c9fbfbd95c jim-eventloop for MinGW-w64
Use JIM_WIDE_MODIFIER for the sscanf format, and apply it for MINGW32 as
well as other Windows environments.  (Microsoft doesn't conform to the
C99 standard, and uses "%I64d" not "%lld" for "long long".)

NB: __MINGW32__ should work on both w32 and w64,.

David Brownell cb7965da15 xscale: better fix for debug_handler.bin
Generate a C struct with the data, and use that, instead of an
assembly language file.  The assembly language causes issues on
Darwin and MS-Windows, which don't necessarily use GNU AS; or
if they do, don't necessarily use its ELF syntax.

It's also better in two other ways:  fewer global symbols; and
the init-time size check gets optimized away at compile time.
(Unless it fails, in which case bigger chunks of the file vanish.)

David Brownell bc792857a5 doc updates to match "help" better
This makes the documentation a closer match to "help" output:

 - "pathmove" somehow was not documented in the User's Guide

 - "jtag_nsrst_assert_width" and "jtag_ntrst_assert_width"
   are new; both needed descriptions.

 - Removed two undocumented and fairly useless script mechanisms:
    * production/production_info/production_test ... using it,
      requires replacing everything; so having it adds no value.
    * cpu ... way out of date; hopeless to keep that current

Note that anyone using that "production" stuff already defines
their own procedures, and can keep using them with no change.

David Brownell 5e837387aa simplify XScale debug handler installation
Load the XScale debug handler from the read-only data section
instead of from a separate file that can get lost or garbaged.
This eliminates installation and versioning issues, and also
speeds up reset handling a bit.

Plus some minor bits of cleanup related to loading that handler:
comments about just what this handler does, and check fault codes
while writing it into the mini-icache.

The only behavioral changes should be cleaner failure modes after
errors during handler loading, and being a bit faster.

NOTE:  presumes GNU assembly syntax, with ".incbin"; and ELF,
because of the syntax of the ".size" directive.

David Brownell 9f6c23f479 more xscale cleanup (mostly removing JTAG hooks)
Streamline/shrink some needless JTAG stuff:

 - Use #defines for the JTAG instructions; they can't ever change
 - Remove an unused (!) shadow of tap->ir_length
 - Stop using a copy of target->tap
 - Don't bother saving the variant after sanity checking ir_length

Also, make target_create() work as on other targets:  build the
register cache later, making init_target() no longer be a NOP.
Handle malloc failure; remove a comment that was obsoleted by the
not-so-new target syntax.
