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/arm/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/arm/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/arm/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/arm/Makefile#dc319d05 Stop using STATIC_CFLAGS.This was added in r293648 to pass -mlong-calls for crt1.o and gcrt1.o.The use of -mlong-calls was removed in r358851 for LLVM 10.0, leavingSTATIC_CFLAGS empty.Sponsored by: DARPADifferential Revision: https://reviews.freebsd.org/D25305 List of files: /freebsd-14.2/lib/csu/arm/Makefile Mon, 29 Jun 2020 17:19:08 +0000 John Baldwin <jhb@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/arm/Makefile#85a2ea3f Only include object files from .ALLSRC when linking crt1 objects.Reported by: np, peterjReviewed by: kib, emasteSponsored by: DARPADifferential Revision: https://reviews.freebsd.org/D25469 List of files: /freebsd-14.2/lib/csu/arm/Makefile Fri, 26 Jun 2020 19:46:30 +0000 John Baldwin <jhb@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/arm/Makefile#99db5849 Always compile the brand and ignore init ELF notes standalone.Reviewed by: kibSponsored by: DARPADifferential Revision: https://reviews.freebsd.org/D25374 List of files: /freebsd-14.2/lib/csu/arm/Makefile Wed, 24 Jun 2020 17:54:24 +0000 John Baldwin <jhb@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/arm/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/arm/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/arm/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/arm/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/arm/Makefile#84eacaf7 Use -mlong-calls to build crt1.o and gcrt1.o.

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/arm/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/arm/Makefile#a22748db Stop calling _init/_fini methods from crt1 for dynamic binaries.

However, newerversions of binutils (after 2.16.90) require the section to be of NOTEtype, to guarantee that the .note.ABI-tag section correctly ends up inthe first page of the final executable.Unfortunately, there is no clean way to tell gcc to use another sectiontype, so crtbrand.c (or the C files that include it) must be compiled inmultiple steps:- Compile the .c file to a .s file.- Edit the .s file to change the 'progbits' type to 'note', for the section directive that defines the .note.ABI-tag section.- Compile the .s file to an object file.These steps are done in the invididual Makefiles for each applicable arch.Reviewed by: kib List of files: /freebsd-14.2/lib/csu/arm/Makefile Thu, 13 Jan 2011 20:44:31 +0000 Dimitry Andric <dim@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/arm/Makefile#5300f787 MFC r200038:Properly support -fPIE by linking PIE binaries with specially-builtScrt1.o instead of crt1.o, since the later is built as non-PIC.Separate i386-elf crt1.c into the pure assembler part and C code,supplying all data extracted by assembler stub as explicit parameters.Hide and localize _start1 symbol used as an interface between asm andC code.
