[deliverable/binutils-gdb.git] / libctf / ChangeLog

2021-01-05  Nick Alcock  <nick.alcock@oracle.com>

	* ctf-impl.h (struct ctf_next) <u.ctn_next>: Move to...
	<ctn_next>: ... here.
	* ctf-util.c (ctf_next_destroy): Unconditionally destroy it.

	members, and a normal member after the end.
	* testsuite/libctf-lookup/struct-iteration.c: Verify that
	ctf_member_count is consistent with the number of successful returns
	from a non-recursive ctf_member_next.
	* testsuite/libctf-lookup/struct-iteration-*: New, test iteration
	over struct members.
	* testsuite/libctf-lookup/struct-lookup.c: New test.

	* configure.ac (BFD_LIBADD): Remove.
	(BFD_DEPENDENCIES): Likewise. Remove associated cases.
	(SHARED_LIBADD): Rename to...
	(CTF_LIBADD): ... this.  Stick in a suitable libiberty even when
	linking statically.
	* Makefile.am (libctf_nobfd_la_LIBADD): Adjust accordingly.
	libctf uses libintl.

2021-01-05  Nick Alcock  <nick.alcock@oracle.com>

	* ctf-decl.c (ctf_decl_push): Exclude slices from the decl stack.

	Get the errno value for non-representable types right.  Do not print
	bitfield info for non-bitfields.  Improve the format and indentation
	of other type output.  Shuffle spacing around to make all indentation
	either 'width of column' or 4 chars.

	ctf_dump_format_type. Don't trim off excess linefeeds now we no
	longer generate them.  Dump enumerated types.

2021-01-05  Nick Alcock  <nick.alcock@oracle.com>

	* ctf-dump.c (ctf_dump_objts): Dump by calling ctf_dump_format_type.
	(ctf_dump_format_type): Don't emit the size for function objects.
	Dump the element type of arrays like we dump the pointed-to type of
	pointers, etc.

2021-01-05  Nick Alcock  <nick.alcock@oracle.com>

	* ctf-dump.c (ctf_dump_format_type): Add 0x to hex type IDs.
	(ctf_dump_header): Add 0x to the hex magic number.
	(ctf_dump_str): Add 0x to the hex string offsets.

	(ctf_dump_member): Align output depending on the width of the type
	ID being generated.  Use printf padding, not a loop, to generate
	indentation.
