2022-09-28This commit implements the Object Shapes technique in CRuby.Jemma Issroff
Object Shapes is used for accessing instance variables and representing the "frozenness" of objects. Object instances have a "shape" and the shape represents some attributes of the object (currently which instance variables are set and the "frozenness"). Shapes form a tree data structure, and when a new instance variable is set on an object, that object "transitions" to a new shape in the shape tree. Each shape has an ID that is used for caching. The shape structure is independent of class, so objects of different types can have the same shape. For example: ```ruby class Foo def initialize # Starts with shape id 0 @a = 1 # transitions to shape id 1 @b = 1 # transitions to shape id 2 end end class Bar def initialize # Starts with shape id 0 @a = 1 # transitions to shape id 1 @b = 1 # transitions to shape id 2 end end foo = Foo.new # `foo` has shape id 2 bar = Bar.new # `bar` has shape id 2 ``` Both `foo` and `bar` instances have the same shape because they both set instance variables of the same name in the same order. This technique can help to improve inline cache hits as well as generate more efficient machine code in JIT compilers. This commit also adds some methods for debugging shapes on objects.

2022-09-20YJIT: Support MAKE=bmake for release buildAlan Wu
This add support for bmake, which should allow building with `configure --enable-yjit` for the BSDs. Tested on FreeBSD 13 and on macOS with `configure MAKE=bmake` on a case-sensitive file system. It works by including a fragment into the Makefile through the configure script, similar to common.mk. It uses the always rebuild approach to keep build system changes minimal.

2022-09-17Always generate non-empty revision.hTakashi Kokubun
Non-GNU make seems to generate empty revision.h, but it doesn't make sense since https://github.com/ruby/ruby/pull/6382. Also the $(HAVE_BASERUBY:yes=tmp) hack doesn't seem to be working on OpenBSD. I'll remove it to focus on fixing RubyCI first, and then deal with baseruby-missing environments. At least a snapshot should have revision.h and it might work fine though.

2022-09-01New constant caching insn: opt_getconstant_pathJohn Hawthorn
Previously YARV bytecode implemented constant caching by having a pair of instructions, opt_getinlinecache and opt_setinlinecache, wrapping a series of getconstant calls (with putobject providing supporting arguments). This commit replaces that pattern with a new instruction, opt_getconstant_path, handling both getting/setting the inline cache and fetching the constant on a cache miss. This is implemented by storing the full constant path as a null-terminated array of IDs inside of the IC structure. idNULL is used to signal an absolute constant reference. $ ./miniruby --dump=insns -e '::Foo::Bar::Baz' == disasm: #<ISeq:<main>@-e:1 (1,0)-(1,13)> (catch: FALSE) 0000 opt_getconstant_path <ic:0 ::Foo::Bar::Baz> ( 1)[Li] 0002 leave The motivation for this is that we had increasingly found the need to disassemble the instructions between the opt_getinlinecache and opt_setinlinecache in order to determine the constant we are fetching, or otherwise store metadata. This disassembly was done: * In opt_setinlinecache, to register the IC against the constant names it is using for granular invalidation. * In rb_iseq_free, to unregister the IC from the invalidation table. * In YJIT to find the position of a opt_getinlinecache instruction to invalidate it when the cache is populated * In YJIT to register the constant names being used for invalidation. With this change we no longe need disassemly for these (in fact rb_iseq_each is now unused), as the list of constant names being referenced is held in the IC. This should also make it possible to make more optimizations in the future. This may also reduce the size of iseqs, as previously each segment required 32 bytes (on 64-bit platforms) for each constant segment. This implementation only stores one ID per-segment. There should be no significant performance change between this and the previous implementation. Previously opt_getinlinecache was a "leaf" instruction, but it included a jump (almost always to a separate cache line). Now opt_getconstant_path is a non-leaf (it may raise/autoload/call const_missing) but it does not jump. These seem to even out. Notes: Merged: https://github.com/ruby/ruby/pull/6187

2022-08-15Optimize Marshal dump/load for large (> 31-bit) FIXNUM (#6229)John Hawthorn
* Optimize Marshal dump of large fixnum Marshal's FIXNUM type only supports 31-bit fixnums, so on 64-bit platforms the 63-bit fixnums need to be represented in Marshal's BIGNUM. Previously this was done by converting to a bugnum and serializing the bignum object. This commit avoids allocating the intermediate bignum object, instead outputting the T_FIXNUM directly to a Marshal bignum. This maintains the same representation as the previous implementation, including not using LINKs for these large fixnums (an artifact of the previous implementation always allocating a new BIGNUM). This commit also avoids unnecessary st_lookups on immediate values, which we know will not be in that table. * Fastpath for loading FIXNUM from Marshal bignum * Run update-deps Notes: Merged-By: jhawthorn <john@hawthorn.email>
