2022-08-04YJIT: Add known_* helpers for Type (#6208)John Hawthorn
* YJIT: Add known_* helpers for Type This adds a few helpers to Type which all return Options representing what is known, from a Ruby perspective, about the type. This includes: * known_class_of: If known, the class represented by this type * known_value_type: If known, the T_ value type * known_exact_value: If known, the exact VALUE represented by this type (currently this is only available for true/false/nil) * known_truthy: If known, whether or not this value evaluates as true (not false or nil) The goal of this is to abstract away the specifics of the mappings between types wherever possible from the codegen. For example previously by introducing Type::CString as a more specific version of Type::TString, uses of Type::TString in codegen needed to be updated to check either case. Now by using known_value_type, at least in theory we can introduce new types with minimal (if any) codegen changes. I think rust's Option type allows us to represent this uncertainty fairly well, and should help avoid mistakes, and the matching using this turned out pretty cleanly. * YJIT: Use known_value_type for checktype * YJIT: Use known_value_type for T_STRING check * YJIT: Use known_class_of in guard_known_klass * YJIT: Use known truthyness in jit_rb_obj_not * YJIT: Rename known_class_of => known_class Notes: Merged-By: maximecb <maximecb@ruby-lang.org>

This commit implements Objects on Variable Width Allocation. This allows Objects with more ivars to be embedded (i.e. contents directly follow the object header) which improves performance through better cache locality. Notes: Merged: https://github.com/ruby/ruby/pull/6117
2022-07-12Speed up --yjit-trace-exits code (#6106)Eileen M. Uchitelle
In a small script the speed of this feature isn't really noticeable but on Rails it's very noticeable how slow this can be. This PR aims to speed up two parts of the functionality. 1) The Rust exit recording code Instead of adding all samples as we see them to the yjit_raw_samples and yjit_line_samples, we can increment the counter on the ones we've seen before. This will be faster on traces where we are hitting the same stack often. In a crude measurement of booting just the active record base test (`test/cases/base_test.rb`) we found that this improved the speed by 1 second. This also results in a smaller marshal dump file which sped up the test boot time by 4 seconds with trace exits on. 2) The Ruby parsing code Previously we were allocating new arrays using `shift` and `each_with_index`. This change avoids allocating new arrays by using an index. This change saves us the most amount of time, gaining 11 seconds. Before this change the test boot time took 62 seconds, after it took 47 seconds. This is still too long but it's a step closer to faster functionality. Next we're going to tackle allowing you to collect trace exits for a specific instruction. There is also some potential slowness in the GC code that I'd like to take a second look at.

2022-06-14YJIT: On-demand executable memory allocation; faster boot (#5944)Alan Wu
This commit makes YJIT allocate memory for generated code gradually as needed. Previously, YJIT allocates all the memory it needs on boot in one go, leading to higher than necessary resident set size (RSS) and time spent on boot initializing the memory with a large memset(). Users should no longer need to search for a magic number to pass to `--yjit-exec-mem` since physical memory consumption should now more accurately reflect the requirement of the workload. YJIT now reserves a range of addresses on boot. This region start out with no access permission at all so buggy attempts to jump to the region crashes like before this change. To get this hardening at finer granularity than the page size, we fill each page with trapping instructions when we first allocate physical memory for the page. Most of the time applications don't need 256 MiB of executable code, so allocating on-demand ends up doing less total work than before. Case in point, a simple `ruby --yjit-call-threshold=1 -eitself` takes about half as long after this change. In terms of memory consumption, here is a table to give a rough summary of the impact: | Peak RSS in MiB | -eitself example | railsbench once | | :-------------: | ---------------: | --------------: | | before | 265 | 377 | | after | 11 | 143 | | no YJIT | 10 | 101 | A new module is introduced to handle allocation bookkeeping. `CodePtr` is moved into the module since it has a close relationship with the new `VirtualMemory` struct. This new interface has a slightly smaller surface than before in that marking a region as writable is no longer a public operation. Notes: Merged-By: maximecb <maximecb@ruby-lang.org>
