[Tinycc-devel] Flushing caches before -running a program

[Thomas Preud'homme]

Hi there,

when packaging TinyCC 0.9.26 for Debian I noticed a build failure on arm with 
EABI calling convention. A bit puzzled at the failure after all the testing 
done (this bug didn't show up on my hardware), I then started to investigate.

After some look at the code, I asked for help to fellow Debian Developers and 
one quickly found that the problem came from the lack of flushing of 
instruction and data caches before running a program in the -run mode. I then 
quickly started working on a patch but I needed to know the size of the code 
that was compiled by tcc. So I added a function to return this in tccgen.c but 
I'm not sure it's ok. It adds another public function and it's the only 
function that take a TCCState argument in that file.

I'm thus asking for comments on the patch.

Best regards,

Thomas
