* Wohoo! David McCullough found the bug! His comments follow:Eric Andersen2001-10-051-12/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I had a look at it and you won't believe it was always broken. I'll try and explain it, let me know if it doesn't make sense. * ash calls setjmp, which messes with the stack to look like it has two args instead of one and then jmps (actually falls) into sigsetjmp. BUG * sigsetjmp then saves the registers and "jumps" to __sigset_save, a C function. BUG1 - because the caller pops its args off the stack, a program that changes it's number of args is broken because the caller will not pop the correct number of args. I think that jumping from the sigsetjmp asm to the 'C' code is unsafe but I can't think of an example. Anyway, I have attached what I think is a working fix. The reason this worked without -fomit-frame-pointer is that the _sigset_save 'C' code would restore the stack pointer from %ebp (the frame pointer) and because none of the asm had moded it, when we returned from __sigset_save the stack was back to it's correct position for 1 argument despite our best attempts to stuff it up ;-)

* Added a script to create bits/syscall.h for each arch.Manuel Novoa III2001-06-284-426/+41
| | | | | | | | | | | NOTE!!! This is run by "make -C libc/sysdeps/linux/$(TARGET_ARCH) headers" in the main Makefile, but I only changed libc/sysdeps/linux/i386/Makefile as I had no way of testing it for the other archs. Various arch maintainers, please check and update the corresponding Makefile... or report bugs ;-)... appropriately. You'll also want to "cvs del" syscall.h and add it to a .cvsignore in $(ARCH)/bits. Also added a define to uClibc_config.h, __UCLIBC_USE_UNIFIED_SYSCALL__, and moved i386 unified syscall stuff out of common and into i386/bits/syscalls.h.
* Stub out an initial version. Manuel will be writingEric Andersen2001-06-271-0/+229

| | | | | | all arches till they add in an libc/sysdeps/linux/<arch>/bits/syscalls.h file. Sorry about there, there was no other way... -Erik
* Add the in* and out* functions for i386. Note: the sys/io.h header forManuel Novoa III2001-06-171-0/+171
| | | | | | | | | glibc-2.2.2 actually defines static inline versions for i386, but only provides prototypes for externs for the other archs I looked at. Since uClibc shares this header amongst archs, I stashed the inline defs in bits/io_i386.h and included it when __i386__ was defined. Better solutions are most welcome, but it doesn't clutter sys/io.h too badly and now lilo and the pcmcia tools build against uClibc on i386 without modification.
* I am very proud of myself. I managed to write a working _start forEric Andersen2001-06-152-0/+52

* Add in some more GNU compatible locale stuff. I only implement theEric Andersen2001-05-251-0/+44

* Ok, this should finish off my massive ro-organization. The sourceEric Andersen2001-05-121-3/+2
| | | | | | | | | tree is less messy now (which helps), all libraries are placed into uClibc/lib when compiling, all libraries now use a consistant mechanism for being built, all libraries use a consistant naming scheme where the lib name includes the uClibc version number, which makes ldconfig happy and willing to work with us. -Erik
* Change FILENAME_MAX to be only 255. Max filename on ext2 is 255,Eric Andersen2001-05-071-1/+1
| | | | | | | so there is no reason to allocate 4k. Change working of execvep.c per patch from Matthias Kilian <kili@outback.escape.de> so that there is not a fixed 127 byte buffer. Too easy to overflow... -Erik

* Fix include/errno.h to not use kernel header, and instead use bits/errno.h.Eric Andersen2001-04-063-9/+9
| | | | | | | This required we use _LIBC instead of __LIBC__ to be consistent with glibc. This had some sideffects in sys/syscalls.h. While fixing things, I made everything use __set_errno() for (eventual) thread support. -Erik
