YJIT: Bounds check every byte in the assembler Previously, YJIT assumed that basic blocks never consume more than 1 KiB of memory. This assumption does not hold for long Ruby methods such as the one in the following: ```ruby eval(<<RUBY) def set_local_a_lot #{'_=0;'0x40000} end RUBY set_local_a_lot ``` For low `--yjit-exec-mem-size` values, one basic block could exhaust the entire buffer. Introduce a new field `codeblock_t::dropped_bytes` that the assembler sets whenever it runs out of space. Check this field in gen_single_block() to respond to out of memory situations and other error conditions. This design avoids making the control flow graph of existing code generation functions more complex. Use POSIX shell in misc/test_yjit_asm.sh since bash is expanding `0%//*` differently.

Put YJIT into a single compilation unit For upstreaming, we want functions we export either prefixed with "rb_" or made static. Historically we haven't been following this rule, so we were "leaking" a lot of symbols as `make leak-globals` would tell us. This change unifies everything YJIT into a single compilation unit, yjit.o, and makes everything unprefixed static to pass `make leak-globals`. This manual "unified build" setup is similar to that of vm.o. Having everything in one compilation unit allows static functions to be visible across YJIT files and removes the need for declarations in headers in some cases. Unnecessary declarations were removed. Other changes of note: - switched to MJIT_SYMBOL_EXPORT_BEGIN which indicates stuff as being off limits for native extensions - the first include of each YJIT file is change to be "internal.h" - undefined MAP_STACK before explicitly redefining it since it collide's with a definition in system headers. Consider renaming? 2021-10-01 18:38:39 -04:00
