The attached patch generalizes the use of PIE (all archs are brought in sync that use/mention it: x86/ppc/frv) and makes use of it building the target utils. Tested on x86, ppc should be tested, frv uses -fPIE at one location, but at another place -fpie, I don't know which is correct (could be both) and misses the target addition in Config.in. The test for ppc (requires the earlier sent crt-correction patch to work correctly): enable UCLIBC_PIE_SUPPORT, build uClibc and utils, check: file ./utils/ldd, it should show shared object (instead of executable)
2004-08-21Kill off all support for 'gcc -pg' / 'gprof' style profiling. There is both aEric Andersen
size and performance penalty to profiling applications this way, as well as Heisenberg effects, where the act of measuring changes what is measured. There are better tools for doing profiling, such as OProfile, that do not require gcc to instrument the application code. -Erik

Hello Erik! I have made some cosmetical changes to the files, removed the added SCRT=-fPIC option from building the crt0.S file (but it is a requirement to build them with -fPIC), and changed some comments. I have left the ldso.c patch with PIE_SUPPORT ifdefs, but consider applying it w/o them (see some earlier comment from PaX Team on this issue, as it is considered a bug). To have it work correctly, you'll also need removing COMPLETELY_PIC. One thing is missing: PIE_SUPPORT should be usable only for i386 (for now). Also added the support for propolice protection (that works for me and catches memcpy/strcpy attacks (but needs a special gcc version). Thanks, Peter
2003-12-03Lethal noticed that the generated file gmon-start.S was notEric Andersen
being cleaned up.
2003-11-22Remove SAFECFLAGS. It was a workaround for failures in old awk scriptEric Andersen
used to generate the crti.S and crtn.S files. Since we don't use that anymore, keeping the workaround makes no sense. Furthermore, in most cases, SAFECFLAGS was not picking up all the needed flags, causing crti.o and crtn.o to not be built PIC. Which is very bad. Removing SAFECFLAGS and using CFLAGS fixes that as well.
2003-11-08Darn. Fix compilation for soft-float, which I inadvertantlyEric Andersen
broke a couple of days ago. :-(

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).
2003-10-08Patch from Atsushi Nemoto (with some additions):Eric Andersen
Current uClibc contains only one fpu_control.h and it is i386 version. This is a patch to use platform specific fpu_control.h. All new files come from glibc 2.3.2. This patch is against 0.9.21 but also can be applied to CVS as is.

2003-01-23Update architecture specific support to consistantlyEric Andersen
generate a crt0 and crt1 file. Most arches still need to be updated to call __uClibc_start_main() rather than __uClibc_main().
2003-01-23Update a tiny bitEric Andersen
2003-01-22Update sigaction syscall names to act more like glibc. Fix the x86 sigactionEric Andersen
implementation such that gdb can actually debug signal handlers. Gdb behaves much better now, for example, on multi-threaded apps. -Erik
2002-12-12Based on discussions with Stefan Allius, change it so that we alwaysEric Andersen
build a crt0.o and a crt1.o. crt1.o will support ctors and dtors if such support is enabled. One more gratuitous toolchain support issue is thereby removed... -Erik

2001-07-03remove bits/syscall.h when cleaningDavid Schleef
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.
2001-06-15I am very proud of myself. I managed to write a working _start forEric Andersen
x86 entirely in C -- no asm required. muahahahaha! -Erik
2001-05-26Makefile targets to symlink arch-specific headers into include/ (onlyDavid Schleef
used on mipsel.)
2001-05-12Ok, this should finish off my massive ro-organization. The sourceEric Andersen
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
