I understand that /usr/bin/gcc on FreeBSD 3.X is gcc 2.7.2.X. Please use a release version of EGCS, such as 1.0.3 and 1.1.2, according as documents. GCC 2.7 consumes unnecessary registers in some cases, so it causes an insufficiency of registers. I know, the sensitiveness to ability of C compiler is not desirable.

I don't have any manual for the AT&T assembler syntax, but its mnemonics are easily reasoned by analogy from the MASM syntax (i.e., MOV). > Anyway, I am using the shujit-0.2.10 a.out binary version instead, and > thus my report may be outdated.

The problem may be gone if the shuJIT is compiled with EGCS. The binary distribution of 0.2.10 is compiled with GCC 2.7.X. I'll provide binary distributions with EGCS when I've returned to my home town. Now I'm on a trip. Kazuyuki SHUDO Happy Hacking! Muraoka Lab., School of Sci. & Eng., Waseda Univ.
