* 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.
