Most trivial point, it shaves around 600 bytes from the dynamicbinaries on amd64. Less trivial, the removed code is no longer part ofthe ABI, and we can ship updates to it with libc updates. Right now mostof the csu is linked into the binaries and require us to do somewhattricky ABI compat when it needs to change. For instance, the init_arraychange would be much simpler and does not require note tagging if wehave init calling code in libc.This could be improved more, by splitting dynamic and staticinitialization. For instance, &_DYNAMIC tests can be removed then.Such change, nonetheless, would require building libc three times.I left this for later, after this change stabilizes, if ever.Reviewed by: markjDiscussed with: jrtc27 (some objections, see the review), impTested by: markj (aarch64)Sponsored by: The FreeBSD FoundationMFC after: 3 weeksDifferential revision: https://reviews.freebsd.org/D37220 List of files: /freebsd-14.2/lib/csu/powerpc64/Makefile Sun, 30 Oct 2022 23:47:44 +0000 Konstantin Belousov <kib@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/powerpc64/Makefile#b0ee263d Consolidate duplicated logic in csu Makefiles to lib/csu/Makefile.inc.Reviewed by: kibSponsored by: DARPADifferential Revision: https://reviews.freebsd.org/D25537 List of files: /freebsd-14.2/lib/csu/powerpc64/Makefile Fri, 03 Jul 2020 00:09:41 +0000 John Baldwin <jhb@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/powerpc64/Makefile#99282790 Remove the sed hack for ABI tag notes.The ELF notes compiled in C were placed in a section with the wrong type(SHT_PROGBITS instead of SHT_NOTE).

As the final step,the C compiler generates an object file from the modified assembly output.Currently this last step uses $CC with only $ACFLAGS. However, for otheruses in the tree, $ACFLAGS is meant to include assembly-specific compilerflags that are in addition to $CFLAGS (see default .S.o rulesbsd.suffixes.mk). In particular, external toolchains may requireadditional flags to select a non-default target which will be presentin CFLAGS but not ACFLAGS. To support this while still mitigating theissue with CFLAGS described in r234502, include a modified CFLAGS thatexcludes "-g" when assembling the modified assembly files.Note that normally an assembler ($AS) is used to assemble .s flags toobject files (see bsd.suffixes.mk). However, llvm-based toolchains donot currently have a stand-alone assembler.Reviewed by: impSponsored by: DARPA / AFRLDifferential Revision: https://reviews.freebsd.org/D10085 List of files: /freebsd-14.2/lib/csu/powerpc64/Makefile Fri, 07 Apr 2017 19:53:14 +0000 John Baldwin <jhb@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/powerpc64/Makefile#90b44255 Clang in base now supports -mlongcall, so remove this hackPR: 215947MFC after: 2 weeks List of files: /freebsd-14.2/lib/csu/powerpc64/Makefile Tue, 07 Mar 2017 02:17:38 +0000 Justin Hibbits <jhibbits@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/powerpc64/Makefile#23f6875a Use SRCTOP-relative paths and .CURDIR with :H instead of ".." specified pathsThis implifies pathing in make/displayed outputMFC after: 3 weeksSponsored by: Dell EMC Isilon List of files: /freebsd-14.2/lib/csu/powerpc64/Makefile Fri, 20 Jan 2017 03:52:16 +0000 Enji Cooper <ngie@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/powerpc64/Makefile#de0fbc4d Don't reset CC away from full-pathed gcc.This was breaking the build when using CROSS_TOOLCHAIN=powerpc64-gccSponsored by: EMC / Isilon Storage Division List of files: /freebsd-14.2/lib/csu/powerpc64/Makefile Thu, 24 Mar 2016 21:48:10 +0000 Bryan Drewery <bdrewery@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/powerpc64/Makefile#7c6cc9de Fix installation of 32bit libraries after r288074.FILES is not used when LIBRARIES_ONLY is set, which is used to build andinstall the lib32 sysroot.

So we use clang's integrated assembler instead. (When thecompiler is gcc, it just calls gas, and nothing is different, except oneextra fork.)However, in the .s to .o rules in lib/csu/$ARCH/Makefile, I still passedCFLAGS to the compiler, instead of ACFLAGS, which are specifically forcompiling .s files.In case you are using '-g' for debug info anywhere in your CFLAGS, itcauses the .s files to already contain debug information in the assemblyitself. In the next step, the .s files are also compiled using '-g',and if the compiler is clang, it complains: "error: input can't have.file dwarf directives when -g is used to generate dwarf debug info forassembly code".Fix this by using ${ACFLAGS} for compiling the .s files instead.Reported by: jasoneMFC after: 1 week List of files: /freebsd-14.2/lib/csu/powerpc64/Makefile Fri, 20 Apr 2012 21:00:39 +0000 Dimitry Andric <dim@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/powerpc64/Makefile#cce345c2 Work around a binutils bug on powerpc64 where the TOC would not beproperly reloaded when calling _fini() in large binaries with multipleTOC sections (e.g. GCC), leading to a segmentation fault.
