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-12.1/lib/csu/powerpc/Makefile Fri, 07 Apr 2017 19:53:14 +0000 John Baldwin <jhb@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/lib/csu/powerpc/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-12.1/lib/csu/powerpc/Makefile Fri, 20 Jan 2017 03:52:16 +0000 Enji Cooper <ngie@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/lib/csu/powerpc/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-12.1/lib/csu/powerpc/Makefile Fri, 20 Apr 2012 21:00:39 +0000 Dimitry Andric <dim@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/lib/csu/powerpc/Makefile#4f78aa47 Work around an issue on 32-bit PowerPC, where clang executable can gettoo big, causing 'relocation truncated to fit' errors at link time.Reviewed by: nwhitehorn List of files: /freebsd-12.1/lib/csu/powerpc/Makefile Mon, 16 Apr 2012 21:36:55 +0000 Dimitry Andric <dim@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/lib/csu/powerpc/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-12.1/lib/csu/powerpc/Makefile Thu, 13 Jan 2011 20:44:31 +0000 Dimitry Andric <dim@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/lib/csu/powerpc/Makefile#03dab16e Use default WARNS setting (of 6) for lib/csu.PR: bin/140089Reviewed by: jmallettApproved by: ed (co-mentor) List of files: /freebsd-12.1/lib/csu/powerpc/Makefile Fri, 05 Mar 2010 13:29:05 +0000 Ulrich Spörlein <uqs@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/lib/csu/powerpc/Makefile#c09ba327 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 [1].Hide and localize _start1 symbol used as an interface between asm andC code.In collaboration with: kanInspired by: PR i386/127387 [1]Prodded and tested by: rdivacky [1]MFC after: 3 weeks List of files: /freebsd-12.1/lib/csu/powerpc/Makefile Wed, 02 Dec 2009 16:34:20 +0000 Konstantin Belousov <kib@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/lib/csu/powerpc/Makefile#d2893b16 Drop support for COPY, -c has been the default mode of install(1)for a long time now.Approved by: bde List of files: /freebsd-12.1/lib/csu/powerpc/Makefile Mon, 29 Jul 2002 09:40:17 +0000 Ruslan Ermilov <ru@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/lib/csu/powerpc/Makefile#20200638 Fixed CLEANFILES after bsd.lib.mk sweep.
