2007-09-13  Richard Sandiford  <richard@codesourcery.com>
	    Sandra Loosemore <sandra@codesourcery.com>

	* config/mips/mips.h (SYMBOL_FLAG_MIPS16_FUNC): Delete.
	(SYMBOL_REF_MIPS16_FUNC_P): Delete.
	* config/mips/mips.c (mips_attribute_table): Turn mips16 and
	nomips16 into decl attributes.
	(TARGET_INSERT_ATTRIBUTES): Override.
	(TARGET_MERGE_DECL_ATTRIBUTES): Likewise.
	(TARGET_FUNCTION_ATTRIBUTE_INLINABLE_P): Always return true.
	(mips_mips16_type_p, mips_nomips16_type_p): Delete in favor of...
	(mips_mips16_decl_p, mips_nomips16_decl_p): ...these new functions.
	(mips_comp_type_attributes): Remove mips16 and nomips16 handling.
	(mips_use_mips16_mode_p): Reimplement as a function that takes
	a decl and considers only decl attributes.  If the decl is nested
	function, use its parent attributes.
	(mips_function_ok_for_sibcall): Use mips_use_mips16_mode_p
	instead of SYMBOL_REF_MIPS16_FUNC_P.
	(mips_set_mips16_mode): Move call to sorry here from old
	mips_use_mips16_mode_p.
	(mflip_mips16_entry): New structure.
	(mflip_mips16_htab): New variable.
	(mflip_mips16_htab_hash, mflip_mips16_htab_eq): New functions.
	(mflip_mips16_use_mips16_p, mips_insert_attributes): Likewise.
	(mips_merge_decl_attributes): New function.
	(mips_set_current_function): Reinstate call to mips_set_mips16_mode.
	Use mips_use_mips16_mode_p.
	(mips_output_mi_thunk): Use mips_use_mips16_mode_p instead of
	SYMBOL_REF_MIPS16_FUNC_P.
	(mips_encode_section_info): Don't set SYMBOL_FLAG_MIPS16_FUNC.

gcc/testsuite/
	* gcc.dg/gcc-have-sync-compare-and-swap.c: Skip for -mflip-mips16.
	* gcc.target/mips/mips16-attributes-2.c: New test.
	* gcc.target/mips/mips16-attributes-3.c: Likewise.
	* gcc.target/mips/args-3.c: Skip for -mflip-mips16.  Do not use the
	hard-float asm when __mips16 is defined.
	* gcc.target/mips/atomic-memory-1.c (main): Add a nomips16 attribute.
	* gcc.target/mips/atomic-memory-2.c (main): Likewise.
	* gcc.target/mips/fpcmp-1.c (f1, f2): Likewise.

	* gcc.target/mips/pr26765.c (foo): Likewise.
	* gcc.target/mips/gcc-have-sync-compare-and-swap-1.c: Run for all
	targets, use dg-mips-options instead of dg-options, and use -mgp32
	to force 32-bit mode.
	* gcc.target/mips/gcc-have-sync-compare-and-swap-2.c: Likewise -mgp64
	and 64-bit mode.
	* gcc.target/mips/mips.exp (is_gp32_flag): Return true for -mips32*.
