by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at February 26, 2020 10:16 AM

Interpreter: Change the signature of the core selector send breakpointing routines from taking the receiver to taking a class tag. (Requires corresponding changes in platforms/Cross/vm/dispdbg.h).
Add an accessor for breakLookupClassTag and add couldBeContext:. Comment fetchClassTagOf:. [This was all to track down a bug with ARMv8 do do with register save/restore across the call in ceScheduleScavengeTrampoline that caused contexts to appear where blocks were expected].

Cogit: rename the accessor for codeToDataDelta to getCodeToDataDelta to allow codeToDataDelta to be defined as 0 in the non DUAL_MAPPED_CODE_ZONE regime. Consequently find and fix a slip in NewspeakCogMethod class>>initialize. Don't attempt to take the address of 0 in the DUAL_MAPPED_CODE_ZONE regime.
Fix genLoadCStackPointer(s) to use NativeSPReg

Slang: add support for even and odd.

Simulator:
Extend machine code breakpojnt framework to allow CogMethodSurrogates to function as breakpoints.
Recategorize the breakpoint routines. Fix a slip in Integer>>addBreakpoint:.

by Eliot Miranda (eliot.miranda@gmail.com) at February 26, 2020 03:19 AM

ARMv8: Fix MoveAwRR & MoveRRAw for SP; SP is not allowed as a souerce or target reg in in LDP/STP, so substitute RISCTempReg.
genAlignCStackSavingRegisters:numArgs:wordAlignment: is a noop given the ARMv8 enforces SP alignment on all SP accesses.
Fix bad bug in genRestoreRegs:.

Add suitable inlining directives and simplify the processor-specific opcode generation routines.

Bump the image version to Squeak5.3rc1.

by Fabio Niephaus (code@fniephaus.com) at February 25, 2020 02:28 PM

Fixes an issue with debugging a process at hand, which is used when entering MVC as recovery for Morphic. Example: "[ 3 + 4 ] newProcess debug".

After this fix, the strange re-draw glitches are gone. BUT, the debugger opens only after, for example, opening the world menu once. That's related to #addDeferredUIMessage: and not having the right controller at hand in #enterForEmergencyRecovery. Not that important for 5.3.

Eliminate infinite dialog loop while seeking author's initials.

February 25, 2020 09:59 AM

Fixes a minor regression with the window title font after UI theme changes.

Note that one could have swapped #setDefaultParamters and #replaceBoxes in #applyUserInterfaceTheme (as suggested by ct), BUT #replaceBoxes reads more specific than #setDefaultParameters, so I put it first. Also, the order of those calls should not make a difference.

Robustness in printing register state and decorating assembly.

by Eliot Miranda (eliot.miranda@gmail.com) at February 25, 2020 05:17 AM

- Optimize for system compactness by ensuring the default internal array size of any HashedCollection is not initialized larger than it may ever need to be.
- Let #new: be used to define larger sizes than the minimum, and perform comparably with #new even if the minimum size is specified.

Minor spelling/formatting fix in a progress label.

by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at February 18, 2020 08:12 AM

Small fix in the wizard's labels when installing extra packages. Make all labels appear in the same form, which starts with an uppercase letter and is (more or less) title case.

(Note that, after the release, we might want to re-design #findFeatures in String. That extra #asLowercase destroys information from the original text. But maybe that was intended after all to better cluster features.)

by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at February 18, 2020 08:09 AM

Fix bug in LargeInteger division: instantiation of quotient (quo) may fail and thus require a proper guard.

It may happen: I did report some crash when testing huge integer division at http://smallissimo.blogspot.com/2019/05/tuning-large-arithmetic-thresholds.html

Fix a copy/paste glitch JumpCarry/JumpNoCarry in #setsConditionCodesFor:
We only ever use JumpZero so far, so it's benign.

by Nicolas Cellier (nicolas.cellier.aka.nice@gmail.com) at February 18, 2020 07:51 AM

Fix alternative code generation for highBit via BSR for Spur32:

Previous opcode is a Label, so we cannot test if it setsConditionCodesFor: JumpNegative.
We have to force a CmpCq:R:.
For X64, it's OK, previous opcode is an arithmetic shift.

Fix simulation of primitiveHighBit by sending #numSmallIntegerTagBits to the objectMemory which knows this kind of memory layout detail.

While at it, change the order of BSR registers maskReg -> destReg, like any other CogRTLOpcodes, rather than destReg <- maskReg.

Require Graphics-nice.425

by Nicolas Cellier (nicolas.cellier.aka.nice@gmail.com) at February 17, 2020 04:19 PM

Fixes a simulation bug regarding #doesNotUnderstand:. Don't forget to indicate the correct lookup class.

Steps to reproduce this bug:
1. Debug "42 foo"
2. Step over
The debugger label was: 'MessageNotUnderstood: nil>>foo'.

February 17, 2020 03:48 PM

Expunge the nil protection out of the LayoutFrame.

Those additional states (to be or not to be nil...) are gratuitous complexifications. YAGNI.
Let's initialize all inst var to zero instead.
This will provide a reasonable default (the least surprising one).

leftOffset = rightOffset = 0 ==> pure proportional layout (no nil offset required).

leftFraction = rightFraction ==> pure absolute layout (no nil fraction required)

all zero ==> empty layout.

Every other combination is possible.

Fixes more icon scaling bugs, which I discovered by testing Etoys (and the demo mode).

(Note that all those #scaleIconToDisplay sends can easily be located through the senders tool and later be corrected once we find better way of scaling things up for high-dpi displays. It is also a nice way of documenting those hard-coded values. ^__^)

A SpurMtoNBitImageConverter>>nilWordSize

Have the converter properly void SmalltalkImage classPool at: #WordSize.
We want to void it rather than nil it so that we know that we have some signal of being in a newly converted image. It takes an insignificant amoputn of tme to compute WordSize the first timne, and having this hook could be useful for applications that introduce word-size dependencies the image converters are ignorant of.

Fix compiler bug with cascaded caseOf:[otherwise:] nodes. When an optimized block form is used in a cascade the form's message is sent ensureCanCascade:, whicharranges to send deoptimize to any and all previously optimized blocks in the form. The bug was that ensureCanCascade: failed to identify the brace node in the optimized caseOf:[otherwise:] form and hence neglected to deoptimize the blocks in the case. The fix is to provide both an isBraceNode to make it easy for ensureCanCascade: to identify braces, and BraceNode>>deoptimize: to do the work.

Add quick-check for identity to String>>sameAs: (similar to Character>>sameAs:).

Example:
[MenuIcons smallInspectItIconContents sameAs: MenuIcons smallInspectItIconContents] bench

Before:
1,740,000 per second. 574 nanoseconds per run. 0 % GC time.

After:
94,800,000 per second. 10.5 nanoseconds per run. 0 % GC time.

Fix RunArrayTest>>testAt2 (testing access out of bounds)

Beware, Text depends on this feature of accessing runs out of bounds, because the characterIndex might be past end.

To avoid problems, transform previous #at: implementation into #atPin: and use that in Text.
#atPin: clamps the index in accessible range.

Make AssertionFailure an Error rather than a Halt.

This change is necessary for at least running the SUnit tests suite, otherwise the DecompilerTests hangs in a debugger...

There was a consensus on this decision in squeak-dev thread last november, so let's just do it:
[squeak-dev] Squeak's AssertionFailure vs. SUnit's TestFailure
http://lists.squeakfoundation.org/pipermail/squeak-dev/2019-November/205039.html

For now, keep it resumable. I don't know if reasonable, but like that, AssertionFailure behavior should be mostly unchanged.

ARMv8: Implement MulRR. Fix pcRelativeAddressAt: for negative offsets (computing newMethod et al in external prims).

ARMv8, Implement saveAndRestoreLinkRegUsingCalleeSavedRegNotLiveAtPointOfSendAround: so that mcprim calls work.

Simulation:
Handle trapping BR's. Implement the remaining simulated control transfer support.

Fix report recent instructions for ARMv8 such that registers are included (we must include pc in integerRegisterState).
