New files:
- vg_cachesim.c
- vg_cachesim_{I1,D1,L2}.c
- vg_annotate.in
- vg_cachegen.in
Changes to existing files:
- valgrind/valgrind.in, added option:
--cachesim=no|yes [no]
- Makefile/Makefile.am:
* added vg_cachesim.c to valgrind_so_SOURCES var
* added vg_cachesim_I1.c, vg_cachesim_D1.c, vg_cachesim_L2.c to
noinst_HEADERS var
* added vg_annotate, vg_cachegen to 'bin_SCRIPTS' var, and added empty
targets for them
- vg_main.c:
* added two offsets for cache sim functions (put in positions 17a,17b)
* added option handling (detection of --cachesim=yes which turns off of
--instrument);
* added calls to cachesim initialisation/finalisation functions
- vg_mylibc: added some system call wrappers (for chmod, open_write, etc) for
file writing
- vg_symtab2.c:
* allow it to read symbols if either of --instrument or --cachesim is
used
* made vg_symtab2.c:vg_what_{line,fn}_is_this extern, renaming it as
VG_(what_line_is_this) (and added to vg_include.h)
* completely rewrote the read loop in vg_read_lib_symbols, fixing
several bugs. Much better now, although probably not perfect. It's
also relatively fragile -- I'm using the "die immediately if anything
unexpected happens" approach.
- vg_to_ucode.c:
* in VG_(disBB), patching in x86 instruction size into extra4b field of
JMP instructions at the end of basic blocks if --cachesim=yes.
Shifted things around to do this; also had to fiddle around with
single-step stuff to get this to work, by not sticking extra JMPs on
the end of the single-instruction block if there was already one
there (to avoid breaking an assertion in vg_cachesim.c). Did a
similar thing to avoid an extra JMP on huge basic blocks that are
split.
- vg_translate.c:
* if --cachesim=yes call the cachesim instrumentation phase
* made some functions extern and renamed:
allocCodeBlock() --> VG_(allocCodeBlock)()
freeCodeBlock() --> VG_(freeCodeBlock)()
copyUInstr() --> VG_(copyUInstr)()
(added to vg_include.h too)
- vg_include.c: declared
* cachesim offsets
* exports of vg_cachesim.c
* added four new profiling events (increasing VGP_M_CCS to 24 -- I kept
the spare ones)
* added comment about UInstr.extra4b field being used for instr size in
JMPs for cache simulation
- docs/manual.html:
* Added --cachesim option to section 2.5.
* Added cache profiling stuff as section 7.
