Dear GCC developers, I propose a small C-language extension that allows
embedding full GNU-style .S assembler code (including directives such as
.type, .size, .global, local labels and section directives) directly inside
a C source file as a dedicated block (for example
__asm_section__(".text.critical"){ ... };); this would improve code
locality, reduce the need for separate .S files and related build-system
friction, and let developers keep full assembler syntax next to the
corresponding C functions — important considerations include preserving the
assembler text through the compilation pipeline, handling differences
between assembler/toolchain versions, symbol visibility and correct section
placement, and adding tests to ensure correct emission of .type/.size and
ABI compatibility; please advise whether it is preferable to open a
Bugzilla entry first or to start a design discussion on the developer
mailing list. Best regards, Denis
See <https://gcc.gnu.org/gcc-15/changes.html#c-family>
You can now put asm blocks outside of functions, which I think will do
all that you are asking for here.
