56af1e088d Bug 488018: Propagate errors from tracer to interpreter. r=igor 
Rename JSMonitorRecordingStatus to JSRecordingStatus.  The JSMRS_
prefix becomes JSRS_, accordingly.

Make 'record_' functions return JSRecordingStatus, not bool.  'false'
becomes 'JSRS_STOP'; 'true' becomes 'JSRS_CONTINUE'.  Since subsequent
patches will begin to use more than two values (the next assigns
meaning to JSRS_IMACRO), take care to propagate values to callers
accurately.

Define a new recording status, JSRS_ERROR.  Return it from recording
functions when appropriate.  Check for it at appropriate bottlenecks
in tracer and interpreter.

ABORT_TRACE becomes one of:
. ABORT_TRACE, for when we're simply aborting the recording process
. ABORT_TRACE_ERROR, for aborting due to an error
. ABORT_TRACE_CV, for producing an error message and returning something
  other than JSRS_STOP --- some contexts require boolean values.

Conditionally provide an alternative definition for the
JSRecordingStatus type that cannot be converted to 'bool', so that we
can use the C++ compiler to catch improperly converted code.

Use recording function return value for imacro invocation.  Eliminate
the JSFRAME_IMACRO_START frame flag.  Instead, return JSRS_IMACRO
directly from recording functions.

debdb32ef3 Bug 480132: Clone lexical blocks only when needed. r=igor 
Terminology:

A "script block" is an object of class Block allocated by the byte
compiler and associated with a script.  Script blocks are never
modified, and may be used as a prototype for a "closure block":

A "closure block" is an object of class Block that holds variables
that have been closed over (although we actually leave the variables
on the stack until we leave their dynamic scope).  A closure block is
a clone of a script block (its prototype is a script block).

Adjust the meanings of fp->blockChain and fp->scopeChain:

  fp->blockChain is always the innermost script block in whose static
  scope we're executing.

  fp->scopeChain is the current scope chain, including 'call' objects
  and closure blocks for those function calls and blocks in whose
  static scope we are currently executing, and 'with' objects for with
  statements; the chain is typically terminated by a global object.
  However, as an optimization, the young end of the chain omits block
  objects we have not yet needed to clone.

Closures need fully reified scope chains, so have js_GetScopeChain
reify any closure blocks missing from the young end of fp->scopeChain
by cloning script blocks as needed from fp->blockChain.  Thus, if we
never actually close over a particular block, we never place a closure
block for it on fp->scopeChain.

Have JSOP_ENTERBLOCK and JSOP_LEAVEBLOCK always keep fp->blockChain
current.  When JSOP_LEAVEBLOCK pops a block from fp->blockChain that
has been cloned on fp->scopeChain, pop fp->scopeChain as well.

Remove the JSFRAME_POP_BLOCKS flag, as it is no longer needed.

Ensure that the JIT won't have to create closure blocks or call
js_PutBlockObject; it can't handle those things yet.  Note our current
script block when we begin recording.  Abort recording if we leave
that block; we can't tell in advance whether it will need to be "put"
in future trace invocations.  Leave trace if we call js_GetScopeChain
while in the static scope of lexical blocks.  Remove JIT tests based
on JSFRAME_POP_BLOCKS.

Verify that generators capture the correct value for blockChain.

Add a constructor to JSAutoTempValueRooter for rooting JSObject
pointers.

unnecessary noise.

Most places get stddef.h via jstypes.h or some other header, so we can
just delete #inclusions of jstddef.h.  The exception is jskwgen.h, so
there we explicitly include <stddef.h> instead.

4a36a6b709 Backed out changeset 25f856429db3. Wrong fix. Looks like jstracer.h is not included. We in fact can call methods of TraceRecorder directly. Sigh. I wish we had a try server. 2008-09-01 18:37:04 -07:00
Andreas Gal
fe70cfea9b Introduce js_DeepAbort to be used from jsinterp.cpp, instead of trying to call TraceRecorder->deepAbort directly (453235). 2008-09-01 18:32:41 -07:00

c7604aac4c - Support JSOP_CONDSWITCH's JSOP_CASE and extended-jump-offset JSOP_CASEX variants properly. 
- Fix sleep-deprived constant conditions due to failure to test flags & CMP_TRY_BRANCH_AFTER_COND!
- Use new TraceRecorder::fuseIf that Andreas added in a few more places where the previous try-branch-after-cond logic was open-coded.

453ea3339f If the inner tree cannot be adjusted to match the call site of the outer tree because it uses an int where the outer tree uses a double, trash the inner tree, not the outer one. In CallTree, return the innermost guard we return from, not the outermost one. Jump over at most 1 loop edge that doesn't go back to our own header, not an arbitrary amount. 2008-08-28 14:24:58 -07:00

c466258c18 Limit tree growth to 16 traces per tree to avoid code explosion due to tail duplication (452869, r=danderson). 2008-09-02 23:52:11 -07:00

2316d281a0 Keep unrolling inner loops as long we are not hitting the same inner loop edge twice in a row (452362). 2008-08-27 17:48:15 -07:00
Andreas Gal
cff18f06cd Fix trashing of inner trees. Keep track of trees that call to a tree and flush them as well since they directly embed the code address. Since flushing an inner tree might invalidate the tree we are currently compiling, trees are now trashed in the destructor of TraceRecorder. 2008-08-27 17:25:56 -07:00

eb0c261390 When extending an outer tree from its nesting guard, the guard we actually exited on determines the typemap for the current frame and all inlined frames, whereas the nesting guard is consulted for all type information frames below the current frame. 2008-08-26 01:00:53 -07:00
Andreas Gal
fc5667ef13 Split closeLoop() and compile() and add endLoop(), which omits an always-exit guard (will be used for break statements.) 2008-08-25 15:17:46 -07:00

71b12b53fe Enable outlining. If a loop doesn't connect back to its own header (i.e. break inside the loop), see if the outer loop path can be attached to the inner loop (outerlining). Added test case (failure mode is high number of activated traces in trace-test.js). This test exposes a regression in access-fannkuch. Committing so we can diagnose that separately. 2008-08-23 15:11:38 -07:00

454b252c63 If the outer loop has a value in a float register but the inner tree expects an int, tell the oracle that we want doubles in that slot in the inner tree and trash the inner tree so it gets re-compiled with a matching layout (451673). 2008-08-22 17:31:23 -07:00

e9b635b38a 1. Add activeCallOrGlobalSlot, used by JSOP_NAME, JSOP_CALLNAME, etc. recorders to cope with Call objects on the scope chain, if they represent still-active frames covered by callDepth. 
2. Add builtin for eval, to be optimized further, to handle very short eval'ed programs as found in popular benchmarks.
3. Add common scopeChain TraceRecorder helper, to generate the LIR to load cx->fp->scopeChain.
4. Add ABORT_TRACE to LeaveFrame for clarity.

3a4d105a0f If the outer tree has a slot in an integer register, but the inner tree expects a double, make sure to promote the value before calling the tree, otherwise the inner tree will read the value from the stack incorrectly. 2008-08-20 00:51:56 -07:00

1ee261ca2e Emit the tree call stack setup code before executing the inner tree, otherwise we might see stale references to instructions prior to the call that no longer guarantee certain types (since the inner tree overwrite them.) 2008-08-19 13:11:18 -07:00
Andreas Gal
e79f9ed689 Intern globals per-context, not per tree, which allows transitioning between trees that use globals. The type of all global slots compiled code uses is expected to remain stable, otherwise the entire code cache has to be flushed. Changes to the shape of the global object also flush the code cache. Working for trace-tests.js, but fails math-partial-sum.js 2008-08-19 11:32:36 -07:00
Andreas Gal
535584eecb Add a method to type map that captures missing slots (which have been lazily added to the slot list since the type map was created.) 2008-08-18 07:32:42 -07:00

ef8a6041cc Give root fragments a treeInfo decorator only if the trace was successfully compiled. Otherwise just keep a reference in the recorder and delete it when the recorder is destroyed. Review welcome. The involved state machine is a bit complex. Added lots of asserts as safety net. 2008-08-16 23:43:49 -07:00

d356a10871 Funnel all write-backs to the stack and the global frame through TraceRecorder::writeBack() so we can intercept and manipulate them in one central location. 2008-08-15 14:47:49 -07:00
Andreas Gal
91a71447a9 Change sp_adj in guards to always reflect the current stack depth, so if we enter a trace/loop with something on the stack, sp_adj will reflect always at least that minimum amount. InterpState->sp now always runs in parallel with regs->sp of the current frame. This breaks nesting badly. I really need help with the stack layout logic. 2008-08-15 10:09:36 -07:00
Andreas Gal
e702dc5ac4 When re-importing register values after a tree call, make sure to use the inner tree's nativeStackBase, since we also use the inner tree's sp. 2008-08-13 16:29:59 -07:00
