* ARM: shrink offsetsDavid Brownell2009-11-051-3/+3
| | | | | | | | | | | | | | | | | | Move various embedded target structs to the beginnings of their containers ... pretty much the way C++ or Obj-C would for single inheritance. This shrinks code that accesses those embedded structs by letting common offsets use smaller instructions. Sample before/after sizes (on amd64): 17181 312 0 17493 4455 arm920t.o 16810 312 0 17122 42e2 arm920t.o Where the "after" is the smaller number, with this patch over the ones leveraging that embedding knowledge.

* XScale uses the new inheritance/nesting schemeDavid Brownell2009-11-051-3/+0
| | | | | | | Use target_to_xscale(), replacing needless pointer traversals and simplifying a bunch of code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: provide container_of()David Brownell2009-11-051-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | Provide a cleaner way to handle single inheritance of targets in C, using the same model Linux does: structs containing other structs, un-nested via calls to a "container_of()" macro that are packaged in typesafe inline functions. Targets already use this containment idiom, but make it much more complicated because they un-nest using embedded "void *" pointers ... in chains of up to five per target, which is all pure needless complication. (Example: arm92x core, arm9tdmi, arm7_9, armv4_5 ... on top of the base "target" class.) Applying this scheme consistently simplifies things, and gets rid of many error-prone untyped pointers. It won't change any part of the type model though -- it just simplifies things. (And facilitates more cleanup later on.) Rule of thumb: where there's an X->arch_info void* pointer, access to that pointer can and should be removed. It may be convenient to set up pointers to some of the embedded structs; and shrink their current "*_common" names (annoyingly long). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* xscale: always reload handler after resetDavid Brownell2009-10-251-2/+0
| | | | | | | | | | | | | | | | | | | | Remove needless debug handler state. - "handler_installed" became wrong as soon as the second TRST+SRST reset was issued ... so the handler was never reloaded after the reset removed it from the mini-icache. This fixes the bug where subsequent resets fail on PXA255 (if the first one even worked, which is uncommon). Other XScale chips would have problems too; PXA270 seems to have, IXP425 maybe not. - "handler_running" was never tested; it's pointless. Plus a related bugfix: invalidate OpenOCD's ARM register cache on reset. It was no more valid than the XScale's mini-icache. (Though ... such invalidations might be better done in "SRST asserted" callbacks.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* xscale: better fix for debug_handler.binDavid Brownell2009-10-161-6/+0
| | | | | | | | | | | | | 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.)

* simplify XScale debug handler installationDavid Brownell2009-10-121-0/+6
| | | | | | | | | | | | | | | | | | | 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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* more xscale cleanup (mostly removing JTAG hooks)David Brownell2009-10-121-17/+7
| | | | | | | | | | | | | | | | 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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
