New Revision: 362203
URL: https://svnweb.freebsd.org/changeset/base/362203
Log:
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 the
generated assembly to rewrite the section type. Instead, write the notes
in assembly which permits setting the correct section type directly.
While here, move inline assembly entry points out of C and into assembly
for aarch64, arm, and riscv.

- * For all arches except sparc, gcc emits the section directive for the
- * following struct 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

- *
- * Unfortunately, there is no clean way to tell gcc to use another section type,
- * so this C file (or the C file that includes 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.
