Intel recommends against the use of -Os, and using it seems to produce
incorrect code in many recent versions of Intel's compilers.
js/src/Makefile.in tries to use -Os only with G++, but it tests
INTEL_CC, not INTEL_CXX --- even though almost all the sources are
C++. Check INTEL_CXX instead.
Here's the commit that added this:
1.1764 <benjamin@smedbergs.us> 2007-01-31 08:12
No bug: checking to see which tinderboxes don't have python available.
It seems unlikely that this echo was meant to stay in the configure script.
SpiderMonkey now has its own copy of some of the files from ./config
and ./build. Since there is a decent amount of churn in that area, I
don't want it to become a burden to make merges back and forth. This
patch adds a comment explaining the 'identical if present' policy, and
runs a script to verify that it's actually being observed.
Have js/src/configure create a header file, js-config.h, that records
configure-controlled options that affect the SpiderMonkey API, like
'--enable-threadsafe'. js-config.h is namespace-clean, so it can be
installed with jsapi.h.
This means that clients can configure SpiderMonkey however they like,
and then simply #include "jsapi.h" and have everything work; they
don't have to remember to match their own compiler -D flags with those
SpiderMonkey's configure script chose. For example, mozilla-config.h
needn't concern itself with JS_THREADSAFE.
It seems to me this could also be done by having js-config --cflags
print -D options. The approach taken here seems a bit more robust: if
you can find jsapi.h at all, then you know you're getting the right
settings.
Give SpiderMonkey its own configure script and top-level Makefile.
Adjust js/src/Makefile as appropriate for life as a stand-alone
makefile, instead of a 'make export; make libs'-style Mozilla tier
makefile. Have the configure script accept '--with-nspr-cflags' and
'--with-nspr-libs' options for using an in-tree NSPR. Also accept
'--with-system-nspr', '--with-nspr-prefix', and
'--with-nspr-exec-prefix' flags for using an installed NSPR. Default
to --disable-jemalloc, assuming we don't have that part of the tree
available; have the top-level configure script pass --enable-jemalloc
as needed.
Since we no longer have an export phase to copy header files into
dist/include/js before we build the library, we need to be able to
find nanojit.h in the nanojit directory; fix references in
jsbuiltins.h and jstracer.cpp.
Give SpiderMonkey it its own copies of many of the files from ./config
and ./build. These are all exact copies, except as follows:
. js/src/config/Makefile.in: js/src only has a subset of
js/src/config, and thus a subset of the makefile targets.
. js/src/config/autoconf.mk.in: js/src/configure.in has its own make
variables to set, not set by the top-level configure script, so it
needs a custom automake.mk template.
. js/src/config/make-system-wrappers.pl: a copy from nsprpub/config,
so that we can build without having an NSPR source tree handy.
Invoke js/src/configure from ./configure, passing the values computed
for NSPR_CFLAGS and NSPR_LIBS by the top-level configure script.
Treat js/src as a static directory of the js tier, and create a new
config/js (just a Makefile) to be the js tier's non-static directory.
Let js/src/configure generate SpiderMonkey's makefiles, not
./configure.
Generate a 'js-config' script, which clients can call to find the
CFLAGS and LIBS values necessary to compile and link against an
installed SpiderMonkey library. Don't include the js-config script in
Macintosh packages.
Teach client.mk how to rebuild js/src/configure.
Tell Mercurial to ignore files generated by autoconf in js/src.
Further work:
. Right now, callers must define JS_THREADSAFE when #including jsapi.h.
This is fixed in a subsequent patch.
. js/src/configure is a trimmed copy of ./configure. It could be
trimmed more.
