2011-01-11sim: allow memory maps to default to mapped filesMike Frysinger2-10/+38
I find it annoying when using --memory-mapfile that I also need to look up and manually specify the file size to the following --memory-region option. So make a length of 0 in the following --memory-region trigger an auto-sizing of the map to the length of the file being mapped. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-01-10sim: fix handling of 2nd arg to SIM_AC_OPTION_HARDWAREMike Frysinger2-3/+9
The 2nd arg to SIM_AC_OPTION_HARDWARE is described as "a space separated list of devices that override the defaults" while the 3rd arg is "a space separated list of extra target specific devices". But the macro doesn't seem to treat the 2nd arg this way. Instead, it will always add the default list of devices, and only add the extra target specific devices if the 2nd arg is not specified. So rework the logic slightly to handle the 2nd arg as documented. This shouldn't affect any targets in the tree as no one passes in a non- empty value as the 2nd arg.

2011-01-10sim: add noreturn markings to more hw abort/halt funcsMike Frysinger3-4/+9
These functions either call abort() themselves, or call functions which are already marked noreturn. Either way, they don't return, so mark them as such so calling code can assume this. This fixes some uninitialized warnings due to code paths that end in an abort function. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-01-05sim: tweak load buffer type to avoid signed warningsMike Frysinger2-1/+5
The sim_load_file func creates a buffer with arbitrary data in it (reads it via the bfd). It then passes it on to a sim_write_fn which expects a unsigned char buffer. Since sim_load_file itself doesn't care about the contents, tweak the type to avoid signed mismatch warnings from gcc: common/sim-load.c: In function ‘sim_load_file’: common/sim-load.c:143: warning: pointer targets in passing argument 3 of ‘do_write’ differ in signedness common/sim-load.c:143: note: expected ‘const unsigned char *’ but argument is of type ‘char *’ Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-12-29sim: HW_NALLOC: new alloc helperMike Frysinger2-0/+5
We have malloc (uninitialized buffer), zalloc (zeroed buffer), and nzalloc (zeroed array). But we don't have a way to allocate an uninitialized array. Add a HW_NALLOC to fill this gap. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-12-29sim: HW_NZALLOC: fix arg handlingMike Frysinger2-1/+5
The HW_NZALLOC macro has all caps args for some reason (unlike the other alloc helpers), and ends up not using the "ME" argument since its copy and paste source uses "me". Make all the args lowercase to match the style of all the other args and make it use the correct "me". Signed-off-by: Mike Frysinger <vapier@gentoo.org>

There are options for listing the current device/hw tree and memory regions, but no way to find out at run time all the current mappings. So add a new --map-info option akin to the --memory-info option which displays all the current mappings. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-11-23sim: cast away hw/device differencesMike Frysinger2-0/+8
When building with device and hw support, the sim-core code generates a lot of build time warnings such as: ./../common/sim-core.c: In function 'sim_core_map_attach': ./../common/sim-core.c:198:7: warning: passing argument 1 of 'device_error' from incompatible pointer type ../common/sim-core.h:347:6: note: expected 'struct device *' but argument is of type 'struct hw *' ./../common/sim-core.c:235:7: warning: passing argument 1 of 'device_error' from incompatible pointer type ../common/sim-core.h:347:6: note: expected 'struct device *' but argument is of type 'struct hw *' In reality, these two structures get cast back and forth in the core code already and so are "compatible". So tweak the three functions that generate all of these warnings to include the casts automatically. I know this isn't exactly clean, but the current device/hw ifdef approach is full of landmines itself and I'm not entirely sure how to unscrew it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-11-16sim: dv-sockser: add a write buffer variantMike Frysinger3-4/+18

2010-04-26sim: unify target->subdir handling for default testsMike Frysinger11-248/+461
The testsuite subdir has a note about unifying the target->subdir logic, so do just that. The end goal here is to have `make check` work out of the box without having to delve into dejagnu internals. The target-specific logic is split out of the top level configure.ac file and into a dedicated configure.tgt similar to other subprojects (gdb and ld and etc...) with the difference that this file has to be included at the m4 level instead of the shell level. This is necessary only because autoconf requires AC_CONFIG_SUBDIRS be given a string literal and not a variable value. Then the toplevel and the testsuite configure files pull this in, the sim subdir gets expanded into testsuite/site.exp, and the default sim run code uses this info to set the sim path to the local compiled run file if it hasn't already been specified.
