changelog-9295

基于4个mips核的noc设计

	(md_convert_frag_1): Don't call subseg_change.

Tue Sep 12 10:36:40 1995  Doug Evans  <[e-mail]>

	* config/tc-arm.c (md_atof): Fix debugging printf, and leave it
	out by default.

Mon Sep 11 11:39:11 1995  Ian Lance Taylor  <[e-mail]>

	* doc/configure.in: Remove unused file.

	* app.c (do_scrub_chars): Grab all available spaces at start of
	line before preserving a single space.  Remove state == 0 test
	which will never succeed.
	* macro.c (macro_expand_body): Delete local variables from the
	formal hash table.
	(macro_expand): In MRI mode, stop when whitespace is seen in the
	argument list.

	* sb.c: Include "libiberty.h".

Fri Sep  8 00:27:46 1995  Ian Lance Taylor  <[e-mail]>

	* app.c (do_scrub_chars): In MRI mode, keep a space before a
	possible comment character.
	* config/tc-m68k.c (m68k_ip): In MRI mode, ignore anything after
	an instruction which takes no operands.

	* Makefile.in (install): Don't install gasp in $(tooldir).

	* config/tc-mips.c (macro): Handle a non zero base register for
	M_U{L,S}{D,W,H}_A.

	* macro.c (ISSEP): Remove duplicated `"' character.
 	(get_any_string): Copy some characters for which ISSEP is true:
	';', '>', '(', ')'.  Otherwise we can get in an infinite loop.
	* read.c (s_space): In MRI mode, the expressions stop at the first
	unquoted space.
	(cons_worker): In MRI mode, restore the terminating character at
	the end of the function.

	* read.c (cons_worker): Don't use #elif; old compilers don't
	support it.

Wed Sep  6 21:13:06 1995  Ian Lance Taylor  <[e-mail]>

	* app.c (do_scrub_chars): In MRI mode, silently end quoted strings
	at newline characters.  In MRI mode, always keep spaces in the
	operands field.  In MRI mode, treat a line comment character as a
	regular comment character following a space.
	* cond.c (ignore_input): Use strncasecmp rather than strncmp when
	looking for special pseudo-ops.
	* read.c (cons_worker): In MRI mode, the expressions stop at the

	* configure.in: When testing for a free() declaration in system
	header files, cast the address to a function pointer, not to an
	integer.

	* write.c (fix_new_internal): Call TC_INIT_FIX_DATA if TC_FIX_TYPE
	is defined.  Don't initialize fx_bsr.  Verify that fx_size field
	is wide enough to hold stored value.
	* write.h (struct fix): Change tc_fix_data to type TC_FIX_TYPE if
	that is defined, otherwise omit it.  Delete fx_bsr.  Change
	fx_size to unsigned char.

	macros.
	* config/tc-ns32k.h (TC_FIX_TYPE, fx_bsr, TC_INIT_FIX_DATA): New
	macros.
	* config/tc-hppa.h (TC_FIX_TYPE): Define as PTR.

	* config/tc-i860.c (md_apply_fix): Delete code for checking
	fx_im_disp, and for handling non-zero values, since it never gets
	set after being initialized to zero.

	* write.h (struct fix): Make fx_im_disp always 2 bits, since the
	only tc-* files actually using it need that much.

	NS32K changes from Ian Dall:
	* configure.in: Treat ns32k-pc532-ux* like ns32k-pc532-mach*, and
	ns32k-pc532-lites* like ns32k-pc532-netbsd*.
	* config/tc-ns32k.h (LOCAL_LABELS_FB): Define to 1.
