[Tinycc-devel] x86_64: shared libs

[Michael Matz]

Hi,

I just pushed some things [1] to mob that make shared libs on x86-64 linux 
sort of working (well, in my little tests).  It's not 100% conformant to 
the ABI yet, but hey, its late here :)  i386 could now use some cleanups 
as well (so that it really generates PIC code, not that unsharing 
text-reloc containing code it currently emits).  I have checked x86-64 (no 
testsuite bugs) and i386 (no _additional_ testsuite bugs), but not ARM. 
I tried to not change the latter, although it also contains dubious code 
(OTOH it currently doesn't support generated shared libs at all, so ...), 
but I might have unintentionally broken stuff.

I had to extend struct sym_attr to contain a full plt_offset, not just a 
flag, it's really required.  Shouldn't be too bad as it's created only for 
symbols that really take part in dynamic linking.

Testing appreciated (hi Arnold :) ).


Ciao,
Michael.
