Thank you for responding with the answer.
I guess it's documented somewhere, and I tried to find out that way,
but failed. I looked in the tcc git root directory README file, the
man page, the TODO, the wikipedia page
https://en.wikipedia.org/wiki/Tiny_C_Compiler,
https://bellard.org/tcc/, https://bellard.org/tcc/tcc-doc.html, and
tried using Google and Bing with no luck. I tried grepping the source
and only found one file, ./elf.h, that was non-windows-centric and
mentioned models, but they didn't seem to indicate what model is used.
It did menion huge model though:
#define SHN_PARISC_HUGE_COMMON 0xff01 /* Common blocks in huge model. */
which is why I asked the original question.
Perhaps in the future when the README is updated a note could be added
to say that at least for now, for 64 bit code on AMD64/INTEL64
systems, tcc generates small model code exclusively?
