* csu: move common code to libcKonstantin Belousov2023-03-112-26/+7
| | | | | | | | | | | | | | | | | | | | | | Why? Most trivial point, it shaves around 600 bytes from the dynamic binaries on amd64. Less trivial, the removed code is no longer part of the ABI, and we can ship updates to it with libc updates. Right now most of the csu is linked into the binaries and require us to do somewhat tricky ABI compat when it needs to change. For instance, the init_array change would be much simpler and does not require note tagging if we have init calling code in libc. This could be improved more, by splitting dynamic and static initialization. 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.

| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326219

* Rework r234502 to include a modified CFLAGS along with ACFLAGS.John Baldwin2017-04-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | On most architectures crt objects are compiled in a multiple-step process so 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 other uses in the tree, $ACFLAGS is meant to include assembly-specific compiler flags that are in addition to $CFLAGS (see default .S.o rules bsd.suffixes.mk). In particular, external toolchains may require additional flags to select a non-default target which will be present in CFLAGS but not ACFLAGS. To support this while still mitigating the issue with CFLAGS described in r234502, include a modified CFLAGS that excludes "-g" when assembling the modified assembly files. Note that normally an assembler ($AS) is used to assemble .s flags to object files (see bsd.suffixes.mk). However, llvm-based toolchains do not currently have a stand-alone assembler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | way: first they are compiled to assembly, then some sed'ing is done on the assembly, and lastly the assembly is compiled to an object file. This last step is done using ${CC}, and not ${AS}, because when the compiler is clang, it outputs directives that are too advanced for our old gas. So we use clang's integrated assembler instead. (When the compiler is gcc, it just calls gas, and nothing is different, except one extra fork.) However, in the .s to .o rules in lib/csu/$ARCH/Makefile, I still passed CFLAGS to the compiler, instead of ACFLAGS, which are specifically for compiling .s files. In case you are using '-g' for debug info anywhere in your CFLAGS, it causes the .s files to already contain debug information in the assembly itself. 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 for assembly code". Fix this by using ${ACFLAGS} for compiling the .s files instead. Reported by: jasone MFC after: 1 week Notes: svn path=/head/; revision=234502

For all arches except sparc, gcc emits the section directive for the abitag struct in crtbrand.c with a PROGBITS type. However, newer versions of binutils (after 2.16.90) require the section to be of NOTE type, to guarantee that the .note.ABI-tag section correctly ends up in the first page of the final executable. Unfortunately, there is no clean way to tell gcc to use another section type, so crtbrand.c (or the C files that include it) must be compiled in multiple 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 Notes: svn path=/head/; revision=217375
