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/riscv/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/riscv/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/riscv/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/riscv/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/riscv/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/riscv/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/riscv/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/riscv/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). Previously, sed was used on thegenerated assembly to rewrite the section type. Instead, write the notesin assembly which permits setting the correct section type directly.While here, move inline assembly entry points out of C and into assemblyfor aarch64, arm, and riscv.Reviewed by: kibTested on: amd64 (cirrus-ci), riscv64Sponsored by: DARPADifferential Revision: https://reviews.freebsd.org/D25211 List of files: /freebsd-14.2/lib/csu/riscv/Makefile Mon, 15 Jun 2020 19:38:48 +0000 John Baldwin <jhb@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/riscv/Makefile#bdafb02f Process irelocs for statically linked binaries from crt1 on x86.This makes statically linked binaries with ifuncs operational.Reported and tested by: mjgReviewed by: emaste, markjSponsored by: The FreeBSD FoundationApproved by: re (rgrimes)Differential revision: https://reviews.freebsd.org/D17363 List of files: /freebsd-14.2/lib/csu/riscv/Makefile Sat, 13 Oct 2018 23:52:55 +0000 Konstantin Belousov <kib@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/lib/csu/riscv/Makefile#5944f899 Rework r234502 to include a modified CFLAGS along with ACFLAGS.On most architectures crt objects are compiled in a multiple-step processso that sed can be run on the generated assembly. 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/riscv/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/riscv/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/riscv/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/riscv/Makefile#1fdcc5e5 Start support for the RISC-V 64-bit architecture developed by UC Berkeley.RISC-V is a new ISA designed to support computer research and education, andis now become a standard open architecture for industry implementations.This is a minimal set of changes required to run 'make kernel-toolchain'using external (GNU) toolchain.The FreeBSD/RISC-V project home: https://wiki.freebsd.org/riscv.Reviewed by: andrew, bdrewery, emaste, impSponsored by: DARPA, AFRLSponsored by: HEIF5Differential Revision: https://reviews.freebsd.org/D4445 List of files: /freebsd-14.2/lib/csu/riscv/Makefile Fri, 11 Dec 2015 22:55:23 +0000 Ruslan Bukin <br@FreeBSD.org>
