* config/tc-h8300.c (do_a_fix_imm): Don't rely on `short' being 16
bits. Instead explicitly mask and sign extend. Do the 8 bit mask
and sign extend without an if statement.
(build_bytes): Likewise.
2000-05-14 Kazu Hirata <kazu@hxi.com>
* config/tc-h8300.c (do_a_fix_imm): Output a reloc for no
X_add_symbol L_32 case.
2000-05-14 David O'Brien <obrien@FreeBSD.org>
* config/te-freebsd.h: New file.
