* kaem.riscv64: New file.
* lib/linux/riscv64-mes-m2/crt1.M1,
lib/m2/riscv64/ELF-riscv64.hex2,
lib/m2/riscv64/riscv64_defs.M1: New files, imported from M2Lib.c
* lib/linux/riscv64-mes-m2/_exit.c,
lib/linux/riscv64-mes-m2/_write.c,
lib/linux/riscv64-mes-m2/crt1.c,
lib/linux/riscv64-mes-m2/syscall.c: New files, adapted for M2-Planet
calling convention from ...
* lib/linux/riscv64-mes-mescc: ...here
* kaem.run: Move fcntl.h up. Include signal.h.
* build-aux/build.sh.in: Also allow kaem build for riscv64.
* lib/linux/riscv64-mes-mescc/_exit.c,
lib/linux/riscv64-mes-mescc/_write.c,
lib/linux/riscv64-mes-mescc/crt1.c,
lib/linux/riscv64-mes-mescc/syscall-internal.c,
lib/linux/riscv64-mes-mescc/syscall.c: New files. These add support for
building for riscv64-mes-mescc and make it self-hosting.
* lib/riscv64-mes/riscv64.M1: New file. Add set of instruction macros
for RV64. These are all potentially needed by the code generation. I
have made no effort yet to minimize the list of instructions for mes+tcc
compile.
* lib/tests/scaffold/76-pointer-arithmetic.c (main): Use the right sizes
in the test for RISC-V architectures.
* lib/tests/scaffold/7k-for-each-elem.c (main): Same.
* lib/tests/scaffold/85-sizeof.c: Same.
* include/linux/syscall.h (_sys_call5): Declare 5-argument syscall needed
for SYS_renameat2, currently only used on RISC-V64.
* lib/linux/riscv64-mes-gcc/syscall.c (__sys_call5, _sys_call5):
Implement it.
* lib/linux/riscv64-mes-gcc/_exit.c,
lib/linux/riscv64-mes-gcc/_write.c,
lib/linux/riscv64-mes-gcc/crt1.c,
lib/linux/riscv64-mes-gcc/syscall-internal.c,
lib/linux/riscv64-mes-gcc/syscall.c: New files to make it possible
to compile mes for riscv64-mes-gcc.
* lib/riscv64-mes-gcc/setjmp.c: New file.
(setjmp, longjmp): Add dummy implementations. Implementing these for gcc
would be very involved, and does not seem necessary to get mescc to
work.
M1 immediates are limited to 31-bit before they become negative.
* module/mescc/x86_64/as.scm (x86_64:value->r, x86_64:r-cmp-value,
x86_64:r-long-mem-add, x86_64:r-and): Limit M1 immediate to #x80000000.
* lib/tests/scaffold/67-m1-overflow-check.c: New test.
* build-aux/check-mescc.sh (mes_tests): Add it.
Reuported by Andrius Štikonas <andrius@stikonas.eu> via IRC.
* lib/tests/assert/50-assert.c (main): Initialize local f.
* lib/tests/scaffold/21-char-array.c (main): Likewise.
* include/mes/lib.h[__M2__](__call_at_exit,abtod,dtoab,ultoa,
* include/sys/types.h[__M2__]: Fall back to unsigned instead of using
unsigned long.
* include/stdio.h[__M2__](fprintf, fscanf, printf, snprintf, sprintf,
sscanf): Hide prototypes.
* lib/stdlib/exit.c (exit)[__M2__]: Hide call to __call_at_exit.
* lib/linux/read.c (read)[__M2__]: Hide debugging.
* lib/linux/malloc.c (malloc)[__M2__]: Hide alignment.
__mesabi_umod, __mesabi_udiv, __mesabi_uldiv): Hide prototypes.
* scaffold/argv.kaem: Use them together with lib/mes/lib-mini.h instead of
lib/mes/* specializations. Remove --bootstrap-mode from M2-Planet call.
This is a follow-up to commit
bc1fa57851
lib: stat: Use SYS_stat64 for 32bit platforms.
* lib/m2/chmod.c: Update to <arch/syscall.sh>.
* lib/m2/clock_gettime.c: Likewise.
* lib/m2/read.c: Likewise.
Uppercase hex number conversions fail for abtol, strtol, strtoul,
strtoull, atoi, and abtod.
The following patch fixes it. This allows tcc to handle assembly
language, which is necessary to build the Fiwix kernel as part of the
kernel bootstrapping in progress for the live-bootstrap project.
* lib/ctype/isxdigit.c (isxdigit): Also allow A-F.
* lib/mes/abtol.c (abtol): Also cater for A-F.
These inexplicably avoid segfaults with gcc-12.2.0.
* lib/tests/posix/50-open-read.c (main)[__GNUC__ > 11]: Use malloc
instead of local allocated string.
* lib/tests/scaffold/7i-struct-struct.c (main)[__GNUC__ > 11]:
Initialize all fields of struct.
* lib/tests/scaffold/t.c (main): Likewise.
After a letter based digit, number based digits are off.
* lib/mes/abtol.c (abtol): Reset "m" for number based digit.
* lib/tests/stdlib/70-strtoull.c (main): Test it.
* lib/tests/stdlib/90-strtol.c (main): Likewise.
* lib/arm-mes/arm.M1 (mov____%esp,%r3): New macro.
* module/mescc/armv4/as.scm (armv4:r0%r1): Use it to avoid overwriting
%r0 before caling __mesabi_uldiv.
* include/linux/arm/syscall.h: Add support for M2-Planet.
* lib/linux/arm-mes-m2/_exit.c,
lib/linux/arm-mes-m2/_write.c,
lib/linux/arm-mes-m2/crt1.M1,
lib/linux/arm-mes-m2/crt1.c,
lib/linux/arm-mes-m2/syscall.c,
lib/m2/arm/ELF-arm.hex2,
lib/m2/arm/arm_defs.M1: New files.
* build-aux/build.sh.in: Also allow kaem build for ARM.
