1994-12-31Handle .space directive with non-constant operand:Ken Raeburn1-19/+35
* read.c (s_space): Rewrite to handle general expressions. Generate rs_space frags for non-constant values. * write.c (cvt_frag_to_fill): Treat rs_align_code and rs_space like rs_align and rs_org. Verify that fr_offset is non-negative, and force frag type to rs_fill only after assertion checks. (relax_segment): Treat rs_align_code like rs_align. Treat rs_space like rs_org in the first switch; in the second, force the operand to a constant, and use it for the growth size.
1994-11-03Changes from net 2.5.2 release branch:Ken Raeburn1-1/+1
* configure.in: Put AC_DEFINE(sparcv9) on its own line, so that the shell variable settings associated with it are permanent. For CPUs requiring bfd_gas=yes, select it based on CPU only, not individual target names. Handle m68k-hp-hpux*, not just -hpux. * config/tc-z8k.c (tc_coff_symbol_emit_hook): Add dummy argument to match prototype in obj-coff.h. * configure.in: Skip tests for defining WANT_FOPEN_BIN and IBM_COMPILER_SUX. * acconfig.h: Deleted them. * configure, conf.in: Rebuild with autoconf 2.0. * config/go32.cfg, config/vms-conf.h: Updated. * config/tc-m68k.c (md_apply_fix_2, md_convert_frag_1): Always use IBM_COMPILER_SUX version of code, with comments indicating why. * listing.c (file_info): Use text mode when opening file for read. Use "r" directly, no macro. * input-file.c (input_file_open): Don't use FOPEN_RT, just use "r". * read.c (s_include): Ditto. * output-file.c (output_file_create): Try both "wb" and "w", don't bother with FOPEN_* macros. * as.h: Don't include fopen-*.h. * config/alpha-opcode.h: Make "ret" with no operands equivalent to "ret zero,(ra)", to match OSF1 and to be consistent with both one-operand forms. Patches from DJ Delorie: * as.h (alloca): undef alloca before defining it just in case * config/go32.cfg: new file for autoconf values * config/te-go32.h: new file * configure.bat: new for autoconf * config/tc-i386.c (md_assemble): Fix typo in GOTPC check; had = for ==. * configure.in: If target_frag doesn't exist, use /dev/null. * as.c (parse_args): For non-VMS systems, re-add `v' to std_shortopts. Add "verbose" to list of long options. * write.c (adjust_reloc_syms): When generating an absolute section symbol as a placeholder, don't mark it as used in a relocation entry, here. * Makefile.in (comparison): Compare using makefile code from gcc, stripped down to discard subdir stuff and adapted to give a non-zero exit status if either file differs.
