give 'let' declarations debug info. This is part of rdar://15785053.
IRGen is just stubbed out and nothing generates these yet (other than
the sil parser).
Swift SVN r12179
Split 'destructive_switch_enum_addr' into separate 'switch_enum_addr' and 'take_enum_data_addr' instructions. This should unblock some optimization work we would like to do with enums.
Swift SVN r12015
Emphasize the fact that this address is only intended for initialization. When we split destructive_switch_enum_addr, there will be another similar instruction for destructively taking the payload out of an already-initialized enum.
Swift SVN r12000
Introduce the SIL instruction peer_method, which references a method
in the given class or one of its superclasses (but not a subclass). It
IRGen's to objc_msgSendSuper[Stret] (vs. super_method IRGen'ing to
objc_msgSendSuper[Stret]2 for superclass lookup).
Use peer_method for initializer delegation to a foreign initializer
(i.e., an init-family method written in Objective-C) to close the
safety loophole introduced by initializer delegation in r11965. The
loophole still exists, but can only be triggered from Objective-C.
Teach definite initialization that peer_method really isn't a use of
self.
Swift SVN r11992
SIL instruction. Implement IR-gen support for same. Fix
the parsing of SIL string literals to properly unescape them.
SIL-gen still emits UTF8 literals unconditionally.
Swift SVN r11904
The current implementation depends on the target basic block to record the number of argumens, but this is a bad idea because it makes it difficult to modify the argument list.
Swift SVN r11597
- change SILGenFunction to use Cleanup and Implicit return locations for
auto-generated cleanups/returns where sensible.
- Fix a bug in where ConstructorDecl that would return the wrong
source range.
- Move the expected locations of some errors to the end of the function
where they should belong.
Fixes <rdar://problem/15609768> Line tables for classes that don't have
init but just initialize ivars are odd
Swift SVN r11086
Remove the initialize_var instruction now that DI fully diagnoses initialization problems. Change String-to-NSString bridging to explicitly invoke String's default constructor; it was the last remaining user of initialize_var. Remove dead code to emit an implicit default constructor without a body.
Swift SVN r11066
Allow archetype_method to look up a witness from a concrete ProtocolConformance record. This will allow generic specialization to apply to constrained generic functions independent of archetype_method devirtualization. <rdar://problem/14748543>
Swift SVN r10950
Existing uses use a "globalvar" kind. Add a new "rootinit" kind which
will be used for root initializers (i.e. init methods of structs, enums,
and root classes).
Swift SVN r10772
The code here is a simple checklist. It performs the following checks in order:
1. Quick check to see if the kind/number of operands/number of types match up.
2. Comparison all of the types/operands.
3. Finally use a switch to perform specialized per instruction comparisons on
state not represented in the instructions types/operands (i.e. vardecls,
structdecls, etc.).
Additionally the switch is setup so that instructions which have not been fully
implemented in the switch will cause an unreachable to be hit. Once all
instructions have isIdenticalTo implementations (implying the switch is
covered), I will remove the unreachable.
*NOTE* The primary use case for this now is CSE. In CSE we can control which
instructions we process so during the review process I am only going to process
literals for the sake of simplicity (and thus this patch contains only code for
checking literals).
Swift SVN r10743
a FuncDecl. This makes it much more straight-forward for SIL passes to
introduce a new one - without doing name lookup in the builtin module!
Swift SVN r10694
Like GlobalAddrInst, but for SILGlobalVariables. These would become the same instruction when SILGlobalVariable can replace AST-level global references.
Swift SVN r10510
(the same way alloc_box returns two) instead of returning a tuple.
This eliminates a ton of tuple_extract instructions, which just
bloat the generated SIL. This resolves rdar://15378135.
Swift SVN r10416
all the tuple stuff is out of the way. This kicks in 600 times in the
stdlib and ends up shrinking the stdlib by 2500 lines (down to 53209).
Swift SVN r9903
- Introduce emitTupleExtract / emitStructExtract, which fold when their operand is a tuple/struct.
- Rename SILBuilder::createTupleExtractInst -> createTupleExtract, "Inst" isn't used as a suffix.
- Switch capture promotion and DI to use the new functions.
This trims 300 lines out of the stdlib.
Swift SVN r9897
SILFunction that it references. Use this in the mandatory inlining
pass to remove deserialized transparent functions, to clean up the
-emit-sil output of the compiler (and presumably speed up compile
time). This implements rdar://15272652
