Can any body help?


This does not look wrong but if below
CALL JMP.dbghelp.SymLoadModuleEx
you see
add ESP, ...
then SymLoadModuleEx was not declared (it is not in tinycc headers).

Hi,

Yes, that's something on my TODO.  Theoretically having 
runtime_plt_and_got makes code emission a tiny bit faster because 
having a proper PLT and GOT also for -run means first creating and 
second applying intermediate relocations (the _GLOB_DAT and _JUMP_SLOT 
relocs), which is cut short with the hack.  OTOH removing the hack 
would remove deviation depending on output type, so I think it's a 
good idea nevertheless.


Done now.  


Wow, does that look clean.  Thanks !

--- grischka

For x86_64 and ARM, where the latter required me to extend 
the current relocation support to some more cases.  To test the latter I 
used gawk and mpfr, for which I had to add alloca support to ARM.  So 
I'm reasonably sure that my changes don't cause regressions, but from 
reading the code there's still potential to fix more things (and of 
course to implement ARM shared libs).  One of those days ...



Ciao,
Michael.

Yep, I was trying to separate cleanups from implementing features also for 
the commits, makes bisecting a tad easier.  (And of course removing chunks 
of dead code without much else just feels wonderful :) ).
