Thanks, does the following fix things for you, and if so, how many
regions does Emacs report when dumping?
I did not try that patch yet – because I was compiling GNU Emacs from
the same code basis as yesterday, now without the bootstrap option.
And it builds with -Os, and if fails when building the bootstrap
targets with -Os!
I saved all *compilation* buffers. Comparing "make bootstrap with -Os"
with "make with -Os" leads, when I leave away the initial bootstrap
paraphernalia, to these "major differences:
make bootstrap:
make[2]: Leaving directory `.../emacs-24.3.50/lib'
cd lib-src && make all -w \
CC='gcc -std=gnu99' CFLAGS='-g -ggdb3 -H -pipe -fPIC -fno-common -
Os -mcpu=7450 -mtune=G4' CPPFLAGS='-I/sw/include' \
LDFLAGS='-L/sw/lib -v -Wl,-v -Wl,-dead_strip_dylibs -Wl,-
bind_at_load -Wl,-t -L/usr/X11/lib' MAKE='make'
make[2]: Leaving directory `.../emacs-24.3.50/lib-src'
boot=bootstrap-emacs; \
if [ ! -x "src/$boot" ]; then \
cd src; make all -w \
CC='gcc -std=gnu99' CFLAGS='-g -ggdb3 -H -pipe -fPIC -fno-
common -Os -mcpu=7450 -mtune=G4' CPPFLAGS='-I/sw/include' \
LDFLAGS='-L/sw/lib -v -Wl,-v -Wl,-dead_strip_dylibs -Wl,-
bind_at_load -Wl,-t -L/usr/X11/lib' MAKE='make'
BOOTSTRAPEMACS="$boot"; \
fi;
make:
make[1]: Leaving directory `.../emacs-24.3.50/lib'
cd lib-src && make all \
CC='gcc -std=gnu99' CFLAGS='-g -ggdb3 -H -pipe -fPIC -fno-common -
Os -mcpu=7450 -mtune=G4' CPPFLAGS='-I/sw/include' \
LDFLAGS='-L/sw/lib -v -Wl,-v -Wl,-dead_strip_dylibs -Wl,-
bind_at_load -Wl,-t -L/usr/X11/lib' MAKE='make'
make[1]: Leaving directory `.../emacs-24.3.50/lib-src'
boot=bootstrap-emacs; \
if [ ! -x "src/$boot" ]; then \
cd src; make all \
CC='gcc -std=gnu99' CFLAGS='-g -ggdb3 -H -pipe -fPIC -fno-
common -Os -mcpu=7450 -mtune=G4' CPPFLAGS='-I/sw/include' \
LDFLAGS='-L/sw/lib -v -Wl,-v -Wl,-dead_strip_dylibs -Wl,-
bind_at_load -Wl,-t -L/usr/X11/lib' MAKE='make'
BOOTSTRAPEMACS="$boot"; \
fi;
which certainly is not significant. But then there are some during the
dumping step:
make bootstrap:
34 LC_LOAD_DYLIB 52
0x14fc080 (sz: 0x2cf1/ 0x3f0a)
0x1400000 (sz: 0x6b5e4/ 0xfc080)
0x27f8000 (sz: 0x6d58/ 0x7f80)
0x2000000 (sz: 0x6d5600/0x7f8000)
0x17f8000 (sz: 0x3fff/ 0x5000)
make:
34 LC_LOAD_DYLIB 52
0x14fc080 (sz: 0x2558/ 0x3f0a)
0x1400000 (sz: 0x2e950/ 0xfc080)
0x27f8000 (sz: 0x63b8/ 0x7f80)
0x2000000 (sz: 0x639917/0x7f8000)
0x13f3000 (sz: 0x3fff/ 0x5000)
This is just a snapshot from the start, more and subtle differences
follow like for example (same "line numbers"):
0x17b0000 (sz: 0x3fff/ 0x5000)
0x17a9000 (sz: 0x63c7/ 0x7000)
0x17a2000 (sz: 0x63bb/ 0x7000)
0x179d000 (sz: 0x3fff/ 0x5000)
vs.
0x17d4000 (sz: 0x3fff/ 0x5000)
0x13d2000 (sz: 0x3fff/ 0x5000)
0x17cd000 (sz: 0x63bb/ 0x7000)
0x13cd000 (sz: 0x3fff/ 0x5000)
Before I'll try the patch I'll make bootstrap with -O0 so see whether
this works – unless you recommend something different.
BTW, how do I count these regions? On Mac OS X this count is not
directly reported and I have no idea how determine the number.
My tries today were 'make clean', configure ..., make.
