2001-12-23  Richard Henderson  <rth@redhat.com>

	* utils.c (end_subprog_body): Push GC context around
	rest_of_compilation for nested functions.

2001-12-23  Richard Henderson  <rth@redhat.com>

2001-12-23  Florian Weimer  <fw@deneb.enyo.de>

	* gnat-style.texi (Declarations and Types): Remove ancient style
	rule which was mandated by code generation issues.
	
	* gnat-style.texi (header): Add @dircategory, @direntry.

	(general) Add @./@: where approriate, and two spaces after the
	full stop at the end of a sentence.  Use @samp markup when
	referring concrete lexical entities (keywords, attribute names
	etc.), and @syntax for ARM grammar elements. Use @r for English
	text in comments.  Use @emph for emphasis.  Change "if-statements"
	etc. to "if statements" (without @samp). Break long lines.  Make
	casing of section names consistent.
	(Identifiers): Use @samp markup for variable names.
	(Comments): Use @samp markup for comment characters. Line-end
	comments may follow any Ada code, not just statements.  Fix
	misspelling of "Integer" as "integer".
	(Loop statements): Do not use variable name "I", use "J".
	(Subprogram Declarations): Document alignment.
	(Subprogram Bodies, Block statements): Document empty line before
	"begin".

	(Time_Stamp_Mismatch): use CRC_Match for comparison.
	(Set_Source_Table): idem.

	* ali-util.ads:
	(Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
	instead of simple checksum.
	(CRC_Match): new function.
	(CRC_Error): new constant.

	* ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
	a CRC now and not a simple checksum. A CRC uses lower-case hex
	letters, fixes ambiguity in parsing.

	* ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
	is what this variable will store.

	* bcheck.adb: Change reference to chechsum in comments by CRC.
	(Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
	rename All_Checksum_Match to All_CRC_Match. Change due to API
	renaming since now GNAT does not use a simple checksum but a
	CRC using GNAT.CRC32.

	* gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
	now and not anymore a simple checksum.

	* lib-load.adb: Use Source_CRC instead of Source_Checksum in many

	Source_CRC in S initialization.

	* sinput.adb (Source_Checksum): renamed to Source_CRC.

	Update comments for the CRC.

	* types.adb (Hex): Use lowercase for the letter part.

	* types.ads (Get_Hex_String): Returns the hexadecimal representation
	for a word. This is currently used only for CRC. In previous version,
	the checksum was using a representation with all letter being
	upper-case. With the new implementation (using CRC) we do not remove
	the 32th bit of the CRC, so we can have an upper-case starting letter
	in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
	It is ambigous since the CRC was optional and could be followed by
	options like EB, EE. So now this routines uses lower-case letter for
	the hexadecimal representation. Strange enough only lower case letters
	where checked in Scan_ALI (even if this was not a possible case).

	* gnatvsn.ads (Library_Version): changed to 3.15a.

	* s-crc32.ads: Initial version from GNAT.CRC32. This is the version
	for the compiler.

	* s-crc32.adb: Initial version from GNAT.CRC32. This is the version
	for the compiler.

	* ali-util.adb: Redo previous change to avoid using word CRC everywhere
	Add 2001 to copyright notice
	(Accumulate_Checksum): Modify to use System.CRC32.

	* ali-util.ads: Redo changes of previous revision to continue to use
	the word Checksum. Add 2001 to copyright notice.

	* ali.adb: Undo some of previous changes, not needed.
	Keep the change for lower case letters in the checksum.

	* ali.ads: Undo previous change not needed.

	* bcheck.adb: Undo most of previous change, not needed.
	But do use Checksums_Match for checksum comparison.

	* gnatls.adb: Undo most of previous change, not needed.
	But do use Checksums_Match for comparing checksums.

	* lib-load.adb: Undo previous change, not needed.

	* lib-writ.adb: Undo previous change, not needed.

	* lib-writ.ads: Document that checksums use lower case,
	not upper case letters.

	* scans.adb: Undo previous change, not needed

	* scans.ads: Undo previous change, not needed.

	* scn-nlit.adb: Undo previous changes, not needed.

	Also remove a-tags and a-stream from GNAT sources.

	* ali.adb (Scan_ALI): fix typo introduce in latest check-in.
