This version of defined? doesn't seem to be possible to emit anymore.

Use ID instead of GENTRY for gvars. (#3278)

2020-07-03T07:56:44+00:00

Use ID instead of GENTRY for gvars.

Global variables are compiled into GENTRY (a pointer to struct
rb_global_entry). This patch replace this GENTRY to ID and
make the code simple.

We need to search GENTRY from ID every time (st_lookup), so
additional overhead will be introduced.
However, the performance of accessing global variables is not
important now a day and this simplicity helps Ractor development.

Avoid top-level search for nested constant reference from nil in defined?

2019-11-13T06:36:58+00:00

Fixes [Bug #16332]

Constant access was changed to no longer allow top-level constant access
through `nil`, but `defined?` wasn't changed at the same time to stay
consistent.

Use a separate defined type to distinguish between a constant
referenced from the current lexical scope and one referenced from
another namespace.

_leaf_helpers.erb: some functions are not leaf

2019-02-01T04:39:47+00:00

If a function has rb_warning() that is not a leaf because warning
ultimately is a method call of Warning#warn.

If a function has rb_name_error() that is not a leaf because
NameError is allocated, then initialized.  This of course
involves calling NameError#initialize.

These settings are now covered by .dir-locals.el.

2018-12-26T07:23:35+00:00

These erb files are in fact erb comments + plain C.  Adding #line
help us debug in case we have trouble there.

Use friendlier terminology in leaf helpers

[Fix GH-2009]

From: Juanito Fatas

add new instruction attribute called leaf

2018-09-11T09:48:58+00:00

An instruction is leaf if it has no rb_funcall inside.  In order to
check this property, we introduce stack canary which is a random
number collected at runtime.  Stack top is always filled with this
number and checked for stack smashing operations, when VM_CHECK_MODE.
