Dimitar Dimitrov	5109a7bd9b	ld: pru: Fix resource_table output section alignment My commit `261980de18` added alignment for the resource table symbol. But it is wrong. The Linux remoteproc driver loads and interprets the contents of the .resource_table ELF section, not of a table symbol. Without this patch, if the linker happens to output padding for symbol alignment, then the resource table contents as viewed by the kernel loader would "shift" and look corrupted. ld/ChangeLog: * scripttempl/pru.sc (.resource_table): Align the output section, not the first symbol.

Alan Modra	ad77db1c02	CC_FOR_TARGET et al The top level Makefile, the ld Makefile and others, define CC_FOR_TARGET to be a compiler for the binutils target machine. This is the compiler that should be used for almost all tests with C source. There are _FOR_TARGET versions of CFLAGS, CXX, and CXXFLAGS too. This was all supposed to work with the testsuite .exp files using CC for the target compiler, and CC_FOR_HOST for the host compiler, with the makefiles passing CC=$CC_FOR_TARGET and CC_FOR_HOST=$CC to the runtest invocation. One exception to the rule of using CC_FOR_TARGET is the native-only ld bootstrap test, which uses the newly built ld to link a copy of itself. Since the files being linked were created with the host compiler, the boostrap test should use CC and CFLAGS, in case some host compiler option provides needed libraries automatically. However, bootstrap.exp used CC where it should have used CC_FOR_HOST. I set about fixing that problem, then decided that playing games in the makefiles with CC was a bad idea. Not only is it confusing, but other dejagnu code knows about CC_FOR_TARGET. See dejagnu/target.exp. So this patch gets rid of the makefile variable renaming and changes all the .exp files to use the correct _FOR_TARGET variables. CC_FOR_HOST and CFLAGS_FOR_HOST disappear. A followup patch will correct bootstrap.exp to use CFLAGS, and a number of other things I noticed. binutils/ * testsuite/lib/binutils-common.exp (run_dump_test): Use CC_FOR_TARGET and CFLAGS_FOR_TARGET rather than CC and CFLAGS. ld/ * Makefile.am (check-DEJAGNU): Don't set CC to CC_FOR_TARGET and similar.

Alan Modra	af29a8abcf	PR28217, Syntax error when memory region contains a hyphen The saga of commit `40726f16a8` continues. This attacks the problem of switching between SCRIPT and EXPRESSION state lexing by removing the need to do so for phdrs like ":text". Instead {WILDCHAR}* matching, the reason why ":text" lexed as one token, is restricted to within the braces of a section or overlay statement. The new WILD lexer state is switched at the non-optional brace tokens, so ldlex_backup is no longer needed. I've also removed the BOTH state, which doesn't seem to be needed any more. Besides rules involving error reporting, there was just one place where SCRIPT appeared without BOTH, the {WILDCHAR}* rule, three where BOTH appears without SCRIPT for tokens that only need EXPRESSION state, and two where BOTH appears alongside INPUT_LIST. (Since I'm editing the wild and filename rules, removing BOTH and adding WILD can also be seen as renaming the old BOTH state to SCRIPT and renaming the old SCRIPT state to WILD with a reduced scope.) As a followup, I'll look at removing EXPRESSION state from some lexer rules that no longer need it due to this cleanup. PR 28217 * ldgram.y (exp <ORIGIN, LENGTH>): Use paren_script_name. (section): Parse within braces of section in wild mode, and after brace back in script mode. Remove ldlex_backup call. Similarly for OVERLAY. (overlay_section): Similarly.

John Ericson	ab4f385b3c	Deprecate a.out support for NetBSD targets. As discussed previously, a.out support is now quite deprecated, and in some cases removed, in both Binutils itself and NetBSD, so this legacy default makes little sense. `netbsdelf` and `netbsdaout` still work allowing the user to be explicit about there choice. Additionally, the configure script warns about the change as Nick Clifton requested. One possible concern was the status of NetBSD on NS32K, where only a.out was supported. But per [1] NetBSD has removed support, and if it were to come back, it would be with ELF. The binutils implementation is therefore marked obsolete, per the instructions in the last message. With that patch and this one applied, I have confirmed the following: --target=i686-unknown-netbsd --target=i686-unknown-netbsdelf builds completely --target=i686-unknown-netbsdaout properly fails because target is deprecated. --target=vax-unknown-netbsdaout builds completely except for gas, where the target is deprecated.

John Ericson	e28a9225b8	Remove `netbsdpe` support netbsdpe was deprecated in `c2ce831330`. Since then, a release has passed (2.37), and it was marked obselete in `5c9cbf07f3`. Unless I am mistaken, that means we can now remove support altogether. All branches in the "active" code are remove, and the target is additionally marked as obsolete next to the other removed ones for libbfd and gdb. Per [1] from the NetBSD toolchain list, PE/COFF support was removed a decade ago. Furthermore, the sole mention of this target in the binutils commit history was in 2002. Together, I'm led to believe this target hasn't seen much attention in quite a while.

H.J. Lu	9181724704	ld: Cache and reuse the IR archive file descriptor Linker plugin_object_p opens the IR archive for each IR archive member. For GCC plugin, plugin_object_p closes the archive file descriptor. But for LLVM plugin, the archive file descriptor remains open. If there are 3000 IR archive members, there are 3000 file descriptors for them. We can run out of file descriptors petty easily. 1. Add archive_plugin_fd and archive_plugin_fd_open_count to bfd so that we can cache and reuse the IR archive file descriptor for all IR archive members in the archive. 2.
