* YJIT: A64: Use ADDS/SUBS/CMP (immediate) when possible We were loading 1 into a register and then doing ADDS/SUBS previously. That was particularly bad since those come up in fixnum operations. ```diff # integer left shift with rhs=1 - mov x11, #1 - subs x11, x1, x11 + subs x11, x1, #1 lsl x12, x11, #1 asr x13, x12, #1 cmp x13, x11 - b.ne #0x106ab60f8 - mov x11, #1 - adds x12, x12, x11 + b.ne #0x10903a0f8 + adds x12, x12, #1 mov x1, x12 ``` Note that it's fine to cast between i64 and u64 since the bit pattern is preserved, and the add/sub themselves don't care about the signedness of the operands. CMP is just another mnemonic for SUBS. * YJIT: A64: Split asm.mul() with immediates properly There is in fact no MUL on A64 that takes an immediate, so this instruction was using the wrong split method. No current usages of this form in YJIT. --------- Co-authored-by: Maxime Chevalier-Boisvert <maxime.chevalierboisvert@shopify.com>

When Ruby is built with ASAN and RUBY_FREE_AT_EXIT is enabled, the
following error occurs:

During compilation, we write keyword default values into the iseq, so we should mark it to ensure it does not get GC'd. This might fix issues on ASAN like http://ci.rvm.jp/logfiles/brlog.trunk_asan.20240927-194923 ==805257==ERROR: AddressSanitizer: use-after-poison on address 0x7b7e5e3e2828 at pc 0x5e09ac4822f8 bp 0x7ffde56b0140 sp 0x7ffde56b0138 READ of size 8 at 0x7b7e5e3e2828 thread T0 #0 0x5e09ac4822f7 in RB_BUILTIN_TYPE include/ruby/internal/value_type.h:191:30 #1 0x5e09ac4822f7 in rbimpl_RB_TYPE_P_fastpath include/ruby/internal/value_type.h:352:19 ruby#2 0x5e09ac4822f7 in gc_mark gc/default.c:4488:9 ruby#3 0x5e09ac51011e in rb_iseq_mark_and_move iseq.c:361:17 ruby#4 0x5e09ac4b85c4 in rb_imemo_mark_and_move imemo.c:386:9 ruby#5 0x5e09ac467544 in rb_gc_mark_children gc.c:2508:9 ruby#6 0x5e09ac482c24 in gc_mark_children gc/default.c:4673:5 ruby#7 0x5e09ac482c24 in gc_mark_stacked_objects gc/default.c:4694:9 ruby#8 0x5e09ac482c24 in gc_mark_stacked_objects_all gc/default.c:4732:12 ruby#9 0x5e09ac48c7f9 in gc_marks_rest gc/default.c:5755:9 ruby#10 0x5e09ac48c7f9 in gc_marks gc/default.c:5870:9 ruby#11 0x5e09ac48c7f9 in gc_start gc/default.c:6517:13
