2013-01-26buildsys: gen_bits_syscall_h: do not leave undefined SYS_xxx aroundMike Frysinger
If we end up doing '#undef __NR_xxx', we don't want to leave the corresponding SYS_xxx symbol defined. So undef it too. For example, with the ARM EABI layer, we have a bunch of legacy syscalls that we define early on and then later undefine (such as __NR_utime). But we left SYS_utime defined so code that tests for that define before using it would be broken (since it'd be defined to a non-existent symbol).

2013-01-26buildsys: gen_bits_syscall_h: clean up scriptMike Frysinger
Just style changes here to make it more readable. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-01-26buildsys: gen_bits_syscall_h: remove top_builddir referencesMike Frysinger
This script hasn't used this var in a while (it writes to stdout), so drop all mention/usage of it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-01-26buildsys: allow the toolchain to search its dirs for kernel headersMike Frysinger
Setting KERNEL_HEADERS up to the exact path all the time is a pita, especially when the toolchain is often times already configured to do the right thing. So if the user has set that to "", don't force any specific paths. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

pgcc would need a completely different treatment here.

found correctly. Tweak the whitespace of the generated file.
2002-09-05Change <bits/syscall.h> to <bits/sysnum.h>.Miles Bader

2002-07-22Rework syscall handling. Rewrite syscall handlers for x86 and ARM.Eric Andersen
Prepare to kill the UNIFIED_SYSCALL option and instead have it be a per arch thing that is either enabled or not for that arch. -Erik

2001-10-12A small patch from Erwin Authried <eauth@softsys.co.at>Eric Andersen
*) changed ARM crt0.S / crt0pic.S selection -- depends on DOPIC now. *) Minor tweek to syscall definitions
2001-07-03Just take whatever the kernel headers gave us, spaces and all. This isEric Andersen
to accomodate arm, where rmk has made the syscall numbers be very very strangely setup, -Erik
2001-06-28Added a script to create bits/syscall.h for each arch.Manuel Novoa III
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.
