* Addition of a new configure option --enable-lto=yes or --enable-lto=no
Default value is --enable-lto=no, as the build is significantly slower,
so is not appropriate for valgrind development : this should be used
only on buildbots and/or by packagers.
* Some files containins asm functions have to be compiled without lto:
coregrind/m_libcsetjmp.c
coregrind/m_main.c
If these are compiled with lto, that gives undefined symbols at link time.
The files to compile without lto are
coregrind/m_libcsetjmp.c
coregrind/m_main.c
To compile these files with other options, a noinst target lib is defined.
The objects of this library are then added to the libcoregrind.
* memcheck/mc_main.c : move the handwritten asm helpers to mc_main_asm.c.
This avoids undefined symbols on some toolchains. Due to this,
the preprocessor symbols that activate the fast or asm memcheck helpers
are moved to mc_include.h
Platforms with handwritten helpers will also have the memcheck primary
map defined non static.
* In VEX, auxprogs/genoffsets.c also has to be compiled without lto,
as the asm produced by the compiler is post-processed to produce
pub/libvex_guest_offsets.h. lto not producing asm means the generation
fails if we used -flto to compile this file.
* all the various Makefile*am are modified to use LTO_CFLAGS for
(most) targets. LTO_CFLAGS is empty when --enable-lto=no,
otherwise is set to the flags needed for gcc.
If --enable-lto=no, LTO_AR and LTO_RANLIB are the standard AR and RANLIB,
otherwise they are the lto capable versions (gcc-ar and gcc-ranlib).
* This has been tested on:
debian 9.4/gcc 6.3.0/amd64+x86
rhel 7.4/gcc 6.4.0/amd64
ubuntu 17.10/gcc 7.2.0/amd64+x86
fedora26/gcc 7.3.1/s390x
No regressions on the above.
svn merge -r11143:HEAD svn://svn.valgrind.org/valgrind/branches/MACOSX106
There were some easy-to-resolve conflicts.
Then I had to fix up coregrind/link_tool_exe*.in -- those files had been
added independently on both the trunk and the branch, AFAICT. I just
overwrote the trunk versions with the branch versions.

executables. Gets rid of the linker script kludgery and uniformly
uses -Ttext=0x38000000 (or whatever) on Linux, so as to accomodate
both traditional ld and gold. Should fix#193413 although I have
been unable to test it. Using a whole new program seems like
overkill, but this is infrastructure to support static linking of
the tool executables on MacOS too.

- Actually remove the dead docs/images/massif*.png files (this was meant to
happen in r10720).
- Inline $TOOL/docs/Makefile.am into $TOOL/Makefile.am for all 10 tools. 10
fewer Makefile.am files FTW!
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10721
following improvements:
- Arch/OS/platform-specific files are now included/excluded via the
preprocessor, rather than via the build system. This is more consistent
(we use the pre-processor for small arch/OS/platform-specific chunks
within files) and makes the build system much simpler, as the sources for
all programs are the same on all platforms.
- Vast amounts of cut+paste Makefile.am code has been factored out. If a
new platform is implemented, you need to add 11 extra Makefile.am lines.
Previously it was over 100 lines.
- Vex has been autotoolised. Dependency checking now works in Vex (no more
incomplete builds). Parallel builds now also work. --with-vex no longer
works; it's little use and a pain to support. VEX/Makefile is still in
the Vex repository and gets overwritten at configure-time; it should
probably be renamed Makefile-gcc to avoid possible problems, such as
accidentally committing a generated Makefile. There's a bunch of hacky
copying to deal with the fact that autotools don't handle same-named files
in different directories. Julian plans to rename the files to avoid this
problem.
- Various small Makefile.am things have been made more standard automake
style, eg. the use of pkginclude/pkglib prefixes instead of rolling our
own.
- The existing five top-level Makefile.am include files have been
consolidated into three.
- Most Makefile.am files now are structured more clearly, with comment
headers separating sections, declarations relating to the same things next
to each other, better spacing and layout, etc.
- Removed the unused exp-ptrcheck/tests/x86 directory.
- Renamed some XML files.
- Factored out some duplicated dSYM handling code.
- Split auxprogs/ into auxprogs/ and mpi/, which allowed the resulting
Makefile.am files to be much more standard.
- Cleaned up m_coredump by merging a bunch of files that had been
overzealously separated.
The net result is 630 fewer lines of Makefile.am code, or 897 if you exclude
the added Makefile.vex.am, or 997 once the hacky file copying for Vex is
removed. And the build system is much simpler.

I tried using 'svn merge' to do the merge but it did a terrible job and
there were bazillions of conflicts. So instead I just took the diff between
the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed
the added files (no files needed to be 'svn remove'd) and committed.

clearer what they mean:
- They all have VGCONF_ prefixes now, to indicate they come out of
configure.in (and are clearly distinguished from the VGA_/VGO_/VGP_
#defines passed in to C files).
- The ones that refer to the primary *or* secondary platform have _INCLUDES_
in them.
- The ones that are in all-caps have a _CAPS suffix.
So, for example, what was VGP_X86_LINUX is now
VGCONF_PLATFORMS_INCLUDE_X86_LINUX, which is more verbose but also a lot
clearer. The names of the #defines used in the C files (VGA_x86, VGO_linux,
etc) are unchanged.
cputest.c: changed to reflect the Valgrind installation's capabilities,
rather than the machine's capabilities. In particular, if
--enable-only32bit is used on a 64-bit machine, then this program will claim
to only support 32-bits. Also use the VGA/VGO/VGP macros which are clearer
than the __i386__ ones. (This is partially merged from the DARWIN branch.)
configure.in: clean up the comments, distinguish different sections more
clearly, and generally make it more readable.
valgrind.pc.in: try to make this more accurate. I doubt anyone's using it.
It doesn't appear to be set up to handle dual-architecture builds.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@9031
Makefile.am changes for AIX5. Almost all boilerplate stuff fitting in
with the existing factorisation scheme. The only change of interest
is that configure.in now generates automake symbols of name
VGP_platform and VGO_os, whereas previously it just made VG_platform
which was a bit inconsistent with the VGP/VGO/VGA scheme used in C
code.

system that allows multiple copies of valgrind to be built so that we

changes from r4341 through r4787 inclusive). That branch is now dead.
Please do not commit anything else to it.
For the most part the merge was not troublesome. The main areas of
uncertainty are:
- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
and include it in a couple of places. Building etc seems to still
work, but I haven't tried building the documentation.
- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
stuff was moved from -generic to -linux after the branch was created.
I think that is satisfactorily glued back together now.
- Regtests: although this appears to work, no .out files appear, which
is strange, and makes it hard to diagnose regtest failures. In
particular memcheck/tests/x86/scalar.stderr.exp remains in a
conflicted state.
- amd64 is broken (slightly), and ppc32 will be unbuildable. I'll
attend to the former shortly.

Valgrind's dependency on the dynamic linker for getting started, and
instead takes things into its own hands.
This checkin doesn't add much in the way of new functionality, but it
is the basis for all future work on Valgrind. It allows us much more
flexibility in implementation, and well as increasing the reliability
of Valgrind by protecting it more from its clients.
This patch requires some changes to tools to update them to the changes
in the tool API, but they are straightforward. See the posting "Heads
up: Full Virtualization" on valgrind-developers for a more complete
description of this change and its effects on you.

automatic cache configuration detection using the CPUID instruction.
This can be overridden from the command-line if necessary.
vg_include.h:
- added the cache_t type and UNDEFINED_CACHE macro
- added command line args (of type cache_t) allowing manual override of
I1/D1/L2 configuration
- added log2(), which is generally useful
vg_main.c, valgrind.in, cachegrind.in:
- added handling of the new --{I1,D1,L2}=<size>,<assoc>,<line_size>
options
vg_cachesim.c:
- lots of stuff for auto-detecting cache configuration with CPUID.
Only handles Intel and AMD chips at the moment, and possibly not all of
them. Falls back onto defaults if anything goes wrong, and the configs
can be manually overridden from the command line anyway.
- now not printing cache summary stats if verbosity == 0. Still writing
cachegrind.out, though.
vg_cachesim_gen.c:
- new file containing stuff shared by the I1/D1/L2 simulations
vg_cachesim_{I1,D1,L2}:
- removed most of it; each now just calls a macro defined in
vg_cachesim_gen.c
vg_cachegen:
- has been cvs removed as it is no longer needed.
Makefile.am:
- added vg_cachesim_gen.c
- removed vg_cachegen
configure.in:
- removed vg_cachegen

as well as LD_PRELOAD, so as to make our libpthread.so go out of scope
when a child which we don't want to trace, is exec'd. Otherwise the
child can wind up being connected to our libpthread.so but not to
valgrind.so, which is an unworkable combination; you have to be connected

- 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.
