2012-02-16Update sim_fetch_register, sim_store_register for sh and mn10300.Kevin Buettner4-4/+15
Fix compile warnings for sh built on 64-bit hosts.

2012-01-06sim: headers: use abs_srcdir to find helper scriptsMike Frysinger2-2/+9
Trying to run `headers` in an out-of-tree build fails atm due to the relative srcdir paths being used in a location other than where they were setup to be used from. Get abs_srcdir from configure and use that instead where applicable. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-12-31sim: erc32: fix linking against local readline on modern (ncurses) systemsMike Frysinger3-21/+52
The current erc32 configure script only searches for -ltermcap to provide any termcap funcs (which readlines needs). When building against a local readline (which is static), we hit link failures like so: gcc ...-I/-D flags... -o sis \ sis.o exec.o erc32.o func.o help.o float.o \ ../../bfd/libbfd.a ../../opcodes/libopcodes.a \ ../../libiberty/libiberty.a -lz -lnsl \ ../../readline/libreadline.a -lm ../../readline/libreadline.a(display.o): In function 'cr': .../readline/display.c:2486: undefined reference to 'tputs' collect2: ld returned 1 exit status make[2]: *** [sis] Error 1 Use AC_SEARCH_LIBS from gdb's configure.ac as suggested by Joel Brobecker to check for additional termcap providers.

2011-12-30sim: cr16: add ifdefs around undefined syscallsMike Frysinger2-0/+17
The cr16 libgloss port does not define these syscall numbers, so trying to use them results in build failures [1]. The cr16 code already uses ifdefs around a bunch of syscalls, so extend that style to cover the ones that are currently missing. Now we can at least compile.

2011-12-19Work around Solaris bourne shell limitation when building the simJoel Brobecker2-2/+9
Building the sim on a sparc-solaris 2.8 machine fails when configured with no extra sim hardware: > for hw in ; do \ > echo "extern const struct hw_descriptor > dv_${hw}_descriptor[];" ; \ > done >> tmp-hw.h > echo 'const char version[] = "'"`sed q > /[...]/../../gdb/version.in`"'";' > >> version.c-tmp > /bin/sh: -c: line 1: syntax error near unexpected token `;' > /bin/sh: -c: line 1: `for hw in ; do \' > make[3]: *** [hw-config.h] Error 2 The same thing happens with the version of bash that we got from Sun as well (which is very old: 2.03.0(1)-release). The problems comes from the fact that both shells are buggy, and reject the following script: for hw in ; do [...] done The above is what sim/common/Makefile.in tries to execute when generating hw-config.h. In order to allow users to build out of the box on these machines, this patch works around this bug. It does rely on the fact that none of the tokens in SIM_HW contain whitespaces. sim/common/ChangeLog: * Make-common.in (hw-config.h): Work around bug in Solaris 2.8 system bourne shell.
2011-12-03sim: bfin: lookup target strings when tracing system callsMike Frysinger2-10/+41
Parsing target addresses is hard if not generally useless, so use the new cb_get_string function to lookup the associated strings as well. Now the trace output is quickly useful instead of just marginally so. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-12-03sim: export cb_get_string for people to useMike Frysinger2-3/+8
The common sim code provides a useful "get_string" function which reads a C string out of the target's memory space. So rename and export it for other people to use. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-12-03sim: generate build dependencies on the flyMike Frysinger78-233/+7988

2011-11-07sim: dv-cfi: check for posix_fallocateMike Frysinger5-3/+13
Some systems (like OS X) do not have posix_fallocate. Add a configure check for it before we try to use it. This is less work than trying to support old systems. URL: http://sourceware.org/bugzilla/show_bug.cgi?id=13161 Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-10-18sim: rename common/aclocal.m4 to common/acinclude.m4Mike Frysinger55-974/+1099
Automake likes to dump macros automatically used into the aclocal.m4 file, but the common/aclocal.m4 naming prevents that. So rename it to the more normal "acinclude.m4" so the aclocal tool can work. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-10-18sim: move from common.m4 to SIM_AC_COMMONMike Frysinger80-9955/+9569
Now that the sourceware tree generally requires autoconf-2.64, update the sim tree to require that too. This allows us to drop the long standing SIM_AC_COMMON/common.m4 workaround as autoconf 2.64+ seems to work for me. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-10-10sim: dv-cfi: include stdbool.hMike Frysinger2-0/+5
The dv-cfi code uses the bool type but doesn't include the stdbool.h header. I didn't notice for Blackfin targets as the core Blackfin header will include stdbool.h, but most targets don't do this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-10-10sim: dv-cfi: include common headers onlyMike Frysinger2-1/+6
The "devices.h" header is Blackfin-specific, so trying to build dv-cfi for any other target fails. Include the specific hw headers this file needs directly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-10-05sim: merge changes from common.m4 back into SIM_AC_COMMONMike Frysinger2-0/+13
Seems some fixes were added to the common.m4 file but not the SIM_AC_COMMON macro. Keep the two in sync since they're supposed to be the same thing. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-09-29sim: bfin: use store buffer for VIT_MAX insnsMike Frysinger4-2/+63
The VIT_MAX insns can be used in parallel, so we need to use the store buffer so we don't clobber the output register before we get a chance to do a memory store with it. Reported-by: Kai Iskratsch <kai@stella.at> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12sim: include sim-options.h for command prototypeMike Frysinger2-0/+5
The sim_args_command prototype is in sim-options.h, so pull it in directly rather than assuming a common header does it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12sim: fix broken skel configure.ac exampleMike Frysinger2-1/+5
Shell code before AC_INIT will be silently culled, and since the common aclocal.m4 includes inline shell code, the file cannot be included before AC_INIT. So update the example to show people including the file after that rather than before to avoid random breakage. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12sim: use AC_REQUIRE with AC_PROG_CCMike Frysinger2-1/+6
The autoconf guys point out that our usage of AC_PROG_CC in the SIM_AC_COMMON does not jive with their intended use. http://www.gnu.org/software/autoconf/manual/autoconf.html#Expanded-Before-Required So utilize AC_REQUIRE to make the warnings go away and generate the correct code with different autoconf versions.

2011-06-18sim: bfin: handle large shift values with accumulator shift insnsMike Frysinger2-2/+14
When the shift magnitude exceeds 32 bits, the values rotate around (since the hardware is actually a barrel shifter).

2011-06-18sim: bfin: handle odd shift values with shift insnsMike Frysinger2-7/+36
The shift magnitude is a 5-bit signed value. When it is between 0 and 15, then we do the requested shift, but when it is outside of that, we have to do the opposite. That means we flip between lshift and ashiftrt to match the hardware. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
