context. Test contexts are used for the left subexpressions of short-circuited boolean operators. The right subexpressions inherit their expression context from the binary op expression. Compilation of short-circuited operations in effect and test context is straightforward: effect(e0 || e1) = test(e0, L0, L1) L1: effect(e1) L0: test(e0 || e1, L0, L1) = test(e0, L0, L2) L2: test(e1, L0, L1) Because the value of the first subexpression may be needed as the value of the whole expression in a value context, we introduce a hybrid value/test contest (the value is needed if true, but not if false). value(e0 || e1) = value/test(e0, L0, L1) L1: value(e1) L0: The compilation of value/test and test/value (introduced by boolean AND) is: value/test(e0 || e1, L0, L1) = value/test(e0, L0, L2) L2: value/test(e1, L0, L1) test/value(e0 || e1, L0, L1) = test(e0, L0, L2) L2: test/value(e1, L0, L1) Boolean AND is the dual. The AST nodes themselves (not their parents) are responsible for producing the proper result (effect, value, or control flow) depending on their context.

o.x() and o[expr]() other changes: - Fix missing relocation info for StoreIC on global object. - Generate only one common return sequence instead of always appending "return <undefined>" at the end of each function: The first JS return-statement will generate the common return sequence. All other return-statements will generate a unconditional branch to the common return sequence.

The code for .result = (b.y = 99) where b is a global variable is: push [esi+0x17] mov ecx,0xf5c229ad ;; object: 0xf5c229ad <String[1]: b> call LoadIC_Initialize nop mov [esp],eax mov eax,0xc6 mov ecx,0xf5c25c41 ;; object: 0xf5c25c41 <String[1]: y> call StoreIC_Initialize nop mov [esp],eax pop [ebp+0xf4] There is still some room for improvement in the generated code. Other changes: - Replaced switch-statement in FastCodeGenerator::VisitProperty with DropAndMove(...) - Do not emit nop after IC calls on ARM.

context of the expressions they label. Introduce an "unintialized" location to catch failure to assign any location at all. Changed the object literal initialization on ARM to use a Store IC in the same cases where it did on the other platforms. This was required because the location of the literal property name is given an "unitialized" location.

location to an Expression AST node from the node's parent to the node itself. This allows an inherited code generation context from a parent node to be passed arbitrarily far down the tree (eg, the subexpression of a unary not is in the same context as the unary expression itself, the then and else subexpressions of the ternary operator are in the same context as the whole expression, and so forth). We do not yet take advantage of this in the backend (eg, the right subexpression of short-circuited OR is still compiled by using the parent's destination location, rather than the subexpression's itself).

- don't engage the processing thread of CPU profiling until the first time profiling is resumed, this saves us a thread allocation for the majority of users; - don't log shared libraries addresses: this is useless for JS-only profiling, and also consumes time on startup.

String slices from RegExp replace results is now encoded in either one or two smis. Substrings are not used any more. If the existing one smi encoding cannot hold the start/length information two smis are used the first having the negative length and the second having the start. This is in preparation for removing string slices.
