to _dl_setup_stack_chk_guard, as in glibc. SSP requires now binutils-2.16.1 and newer. Add NOT_IN_libc/IS_IN_libc. Began using -DSHARED in uClibc_main.c, there are more candidates in there. Move back dl_protect_relro to it's earlier place.

float_wrapper. I hope that __ceilf and __floorf are not needed anywhere. Use only __finite from s_finite.c, disabled in fpmacros.c. Allow IMA compiling, 2 files: s_lib_version.c and w_cabs.c have to be reworked for complete IMA.

archs lack proper crt1. The Makefiles in extra/scripts are intended to be linked into each dir, where it is necessary to build locally.

objects at once; use :=//$</$^; use CRT_SRC/CRT_OBJ/SCRT_OBJ/CSRC/COBJ/SSRC/SOBJ/MSRC/MOBJ where no more is needed, if only CSRC is present use OBJS directly instead of COBJ; CTOR_TARGETS are created directly in lib; remove unused/unneeded parts. Hope I haven't broken too much.

defer only for shared lib related stuff, because it is optional. Run STRIPTOOL only once. More use of /$^/$<.

Hello Erik,
My patch adding ARM assembly soft-float routines to gcc also changes the
default FPA float word ordering for the saner VFP word ordering which is
also the order anyone would expect on a little endian machine.
Problem is that uClibc curently hardwire floats to big endian (FPA) ordering
in all cases.
Please consider the attached patch to fix this problem.

avoid problems 'hidden symbol' problems. Also handle -lfloat for the
soft-float arm case.

uClibc's libm has isinf/isinff, isnan/isnanf but not finite/finitef.
Here is a patch.

ln.patch:
* Define $(LN) as ln in Rules.mak.
* Change all occurrences of ln into $(LN).
* Change all constructs like (cd path && ln -sf foo/file file)
into $(LN) -sf foo/file path/file. The latter construct is
already used in a number of places so it should not be
an additional compatibility problem.
|
|
rm.patch:
* Define $(RM) as rm -f in Rules.mak and test/Rules.mak
(this is the same definition as gmake uses by default).
* Change all occurrences of rm and rm -f into $(RM).
|
|
install.patch:
* Define $(INSTALL) as install in Rules.mak.
* Change all occurrences of install into $(INSTALL).
* Change all occurrences of mkdir -p into $(INSTALL) -d.
install -d is already used in a number of places so
this should not be an additional compatibility problem.

I found math fpclassify function is broken because FP_XXX definitions
in libm/fp_private.h is incompatible with include/math.h.
Also I noticed fp_private.h and fpmacros.c use many 'long int' for
32bit variables. I think these should be int or u_int32_t.
Here is a patch against 0.9.20.
fp_private.c:
--- fix union members (use u_int32_t instead of 'unsigned long int').
--- remove incompatible FP_XXX definitions (and some unused macros).
fpmacros.c:
--- use FP_NAN instead of FP_QNAN/FP_SNAN.
--- use correct type (int instead of long int).
--- fix union members (use u_int32_t instead of 'unsigned long int').
--- remove unnecessary cast.
Note that I had to remove weak_alias for isnanl,isinfl to compile
patched fpmacroc.c. Is this really needed? Original behavior (using
isnan for isnanl) seems problematic anyway.

only when HAS_FPU is set. If you don't have an FPU
then usm FPU code isn't going to help much...
