| | | | | | | | | | | | | | | type of 'struct stat' and 'struct stat64' so they use consistant types. This change is the result of a bug I found while trying to use GNU tar. The problem was caused by our using kernel types within struct stat and trying to directly compare these values with standard types. Trying an 'if (a < b)' when 'a' is an 'unsigned long' and 'b' is an 'int' leads to very different results then when comparing entities of the same type (i.e. time_t values).... Grumble. Nasty stuff, but I'm glad I got this out of the way now. As a result of this fix, uClibc 0.9.17 will not be binary compatible with earlier releases. I have always warned people this can and will happen. -Erik

* This commit contains a patch from Stefan Allius <allius@atecom.com> to changeEric Andersen2002-10-011-15/+12
| | | | | | | how uClibc handles _init and _fini, allowing shared lib constructors and destructors to initialize things in the correct sequence. Stefan ported the SH architecture. I then ported x86, arm, and mips. x86 and arm are working fine, but I don't think I quite got things correct for mips.

* Manuel and I were looking into a problem with applications failing to linkEric Andersen2002-04-142-0/+7
| | | | | | | | | | (undefined reference to `main') when the .o file containing main was contained in an static library(a '.a' ar archive). It turns out that due to its single pass nature, GNU ld was failing to pull it into the build. This sticks a dummy reference to main() into crt0.o, so that when an application is linked with the main() function in a static library, we can be sure that main() actually gets linked in. -Erik

* 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 ;-)
