- Broke part of m_scheduler off into a new module m_threadstate. It
contains ThreadState, VG_(threads)[] and some basic operations on the
thread table. All simple stuff, the complex stuff stays in m_scheduler.
This avoids lots of circular dependencies between m_scheduler and other
modules.
- Managed to finally remove core.h and tool.h, double hurrah!
- Introduced pub_tool_basics.h and pub_core_basics.h, one of which is
include by every single C file.
- Lots of little cleanups and changes related to the above.
- I even did a small amount of documentation updating.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3944
- Renamed VG_INTERCEPT as VG_REPLACE_FUNCTION to make its purpose
clearer.
- Renamed VG_WRAPPER as VG_NOTIFY_ON_LOAD to make its purpose cleare.
Started calling that stuff "load notification".
- Moved various things into m_redir.c, a much more sensible place for
them. This reduced the number of exported functions overall. Renamed
intercept_demangle() as Z_decode() as part of this.
- Improved the documentation of this stuff, especially in
pub_core_redir.c.
- Got --run-libc-freeres=yes working again. It was doing nothing.
- Renamed vg_inject.so as vg_preload_core.so to match
vg_preload_<tool>.so
- Renamed vg_intercept.c as vg_preloaded.c. (I kept the "vg_" prefix
because this filename can appear in stack traces, so the "vg_" is a
useful hint for users that it belongs to Valgrind.)
- Removed all the Memcheck-specific calls to add_redirect_sym_to_sym()
from VG_(setup_redirect_table)(), instead using VG_REPLACE_FUNCTION in
mac_replace_strmem.c, just like vg_replace_malloc.c. This is the
right way to do it. This required moving some of
coregrind/pub_core_redir.h into the newly added
include/pub_tool_redir.h. add_redirect_sym_to_sym() is no longer
used...
- Now only handing off symbols to m_redir for inspection/decoding after
they have been deemed to be interesting by the symbol table reader.
- Factored out commonality between the add_redirect_*_to_* functions
into add_redirect_X_to_X().
- Added "Zh", meaning '-' ('h' for "hyphen"), to the Z-decoding scheme,
to handle sonames like "ld-linux-x86-64.so.2".
- Added a FAQ explaining the newly found issue of glibc aliasing
sometimes causing the wrong function name to appear in stack traces.
- Added a new regtest strchr.c. It's possible this will fail on some
platforms. If so, an alternative output file can be provided, but
I'd like to see it in practice first.
It's possible that there will be minor breakage on other
platforms/setups, but it should be minimal and easily fixable.
Plus some ordinary cleanups in symtab.c:
- Removed the old optimisation from VG_(addStr)() whereby it kept track
of the previous 5 added strings and avoiding duplicating any of them.
Turns out it was barely having any effect any more, and just
complicated things.
- Made read_symtab() more readable, by introducing a new variable
"sym_name" and introducing the auxiliary function
is_symbol_interesting().
- renamed the module variable 'segInfo' as 'segInfo_list' to make it
more obvious it's a module variable and not just some ordinary local
variable (which was an easy mistake to make).
-----------------------------------------------------------------------------
XXX: [later] remove add_redirect_sym_to_sym, and everything related to
X_to_sym? (ie. only need X_to_addr)
XXX: better function names? all those 'resolved' names...
[later...]

- fixed link to comply with house-style
mc-manual.xml:
- rm'd unhelpful sentence + it's footnote
quick-start-guide.xml:
- fixed up some section ids + xreflabels
so we don't get cool filenames like 'bk01s02.html'.

As a consequence, $PLATFORM/core_platform.h files are no longer necessary,

through the VG_(tdict) function dictionary, rather than using TL_(foo)
functions.
This facilitated the following changes:
- Removed the "TL_" prefix, which is no longer needed.
- Removed the auto-generated files vg_toolint.[ch], which were no longer
needed, which simplifies the build a great deal. Their (greatly
streamlined) contents went into core.h and vg_needs.h (and will soon
go into a new module defining the core/tool interface).
This also meant that tool.h.base reverted to tool.h (so no more
accidentally editing tool.h and not having the changes go into the
repo, hooray!) And gen_toolint.pl was removed. And toolfuncs.def was
removed.
- Removed VG_(missing_tool_func)(), no longer used.
- Bumped the core/tool interface major version number to 8. And I
killed the minor version number, which was never used. The layout
of the ToolInfo struct is such that this should not cause problems.

controlled (rounding user malloc requests up to a multiple of 4).
Subsequent changes to memcheck made it more or less pointless, it is a
time waster in the malloc/free path, and nobody ever used it AFAIK.

I ran out of steam at memcheck/docs/mc_techdocs.html, which is even more
hopelessly out of date. I will note that cacheprof.org is some kind of
dental insurance company now...

converted by Donna. Hooked it into the build system so they are only
built when specifically asked for, and when doing "make dist".
They're not perfect; in particular, there are the following problems:
- The plain-text FAQ should be built from FAQ.xml, but this is not
currently done. (The text FAQ has been left in for now.)
- The PS/PDF building doesn't work -- it fails with an incomprehensible
error message which I haven't yet deciphered.
Nonetheless, I'm putting it in so others can see it.
