Add bound checking to arm, arm64 and riscv64 Checked on: - i386/x86_64 (linux/windows) - arm/arm64 (rapberry pi) - riscv64 (simulator) Not tested for arm softfloat because raspberry pi does not support it. Modifications: Makefile: add arm-asm.c to arm64_FILES add riscv64-asm.c (new file) to riscv64_FILES lib/Makefile: add fetch_and_add_arm.o(new file) to ARM_O add fetch_and_add_arm64.o(new file) to ARM64_O add fetch_and_add_riscv64.o(new file) to RISCV64_O add $(BCHECK_O) to OBJ-arm/OBJ-arm64/OBJ-riscv64 tcc.h: Enable CONFIG_TCC_BCHECK for arm32/arm64/riscv64 Add arm-asm.c, riscv64-asm.c tcctok.h: for arm use memmove4 instead of memcpy4 for arm use memmove8 instead of memcpy8 tccgen.c: put_extern_sym2: for arm check memcpy/memmove/memset/memmove4/memmove8 only use alloca for i386/x86_64 for arm use memmove4 instead of memcpy4 for arm use memmove8 instead of memcpy8 fix builtin_frame_address/builtin_return_address for arm/riscv64 tccrun.c: Add riscv64 support fix rt_getcontext/rt_get_caller_pc for arm tccelf.c: tcc_load_dll: Print filename for bad architecture libtcc.c: add arm-asm.c/riscv64-asm.c tcc-doc.texi: Add arm, arm64, riscv64 support for bound checking lib/bcheck.c: add __bound___aeabi_memcpy/__bound___aeabi_memmove __bound___aeabi_memmove4/__bound___aeabi_memmove8 __bound___aeabi_memset for arm call fetch_and_add_arm/fetch_and_add_arm64/fetch_and_add_riscv64 __bound_init: Fix type for start/end/ad __bound_malloc/__bound_memalign/__bound_realloc/__bound_calloc: Use size + 1 arm-gen.c: add bound checking code like i386/x86_64 assign_regs: only malloc if nb_args != 0 gen_opi/gen_opf: Fix reload problems arm-link.c: relocate_plt: Fix address calculating arm64-gen.c: add bound checking code like i386/x86_64 load/store: remove VT_BOUNDED from sv->r arm64_hfa_aux/arm64_hfa_aux: Fix array code gfunc_prolog: only malloc if n != 0 arm64-link.c: code_reloc/gotplt_entry_type/relocate: add R_AARCH64_LDST64_ABS_LO12_NC relocate: Use addXXle instead of writeXXle riscv64-gen.c: add bound checking code like i386/x86_64 add NB_ASM_REGS/CONFIG_TCC_ASM riscv64-link.c: relocate: Use addXXle instead of writeXXle i386-gen.c/x86_64-gen.c gen_bounds_epilog: Fix code (unrelated) tests/Makefile: add $(BTESTS) for arm/arm64/riscv64 tests/tests2/Makefile: Use 85 only on i386/x86_64 because of asm code Use 113 only on i386/x86_64 because of DLL code Add 112/114/115/116 for arm/arm64/riscv64 Fix FILTER (failed on riscv64) tests/boundtest.c: Only use alloca for i386/x86_64

#ifdef __TINYC__
Call __bound_main_arg at startup This uses a glibc feature present since constructor/destructor support was added. Modify tccrun.c to call constructor with argc, argcv, envp. In lib/bcheck.c use these values to register them in the splay tree. Remove HAS_ENVIRON is lib/bcheck.c as it is not needed any more. Modify win32/lib/crt1.c/win32/lib/dllcrt1.c/win32/lib/wincrt1.c to also call constructor with argc, argcv, envp. While implementing I saw that tccrun did nog call main with envp. Fixed it. Also fix fetch_and_add_arm.S to make it work on armv6 (raspberry pi default).
