<pre wrap="">How to see primitive source these days:
The code is in the VMMaker repository '<a class="moz-txt-link-freetext" href="http://source.squeak.org/VMMaker">http://source.squeak.org/VMMaker</a>'.
For the Spur VM, the package is 'VMMaker.oscog'. For purposes of just
taking a quick look at the code, you can load the latest version
VMMaker.oscog-eem.2079 (this will not exactly corresponding to the version
you are running but here I assume you just want a quick look at what
primitive 105 is doing).
To find the numbered primitive, see CoInterpreter class>>initializePrimitiveTable,
which calls StackInterpreter class>>initializePrimitiveTable, which shows
primitive 105 as #primitiveStringReplace.
The Smalltalk code for this primitive is InterpreterPrimitives>>primitiveStringReplace.
The generated C code for this can be found in the GitHub repository
<a class="moz-txt-link-freetext" href="https://github.com/OpenSmalltalk/opensmalltalk-vm">https://github.com/OpenSmalltalk/opensmalltalk-vm</a>, look for the
primitiveStringReplace function in opensmalltalk-vm/src/vm/gcc3x-cointerpmt.c.

Float>>replaceFrom:to:with:startingAt: says it uses a primitive, but it
seem to fallback to the code in SequenceableCollection. How can I see
the priitive code to see what the issue may be? This is what it says it
does:
replaceFrom: start to: stop with: replacement startingAt: repStart
"Primitive. This destructively replaces elements from start to stop in
the receiver starting at index, repStart, in the collection,
replacement. Answer the receiver. Range checks are performed in the
primitive only. Optional. See Object documentation whatIsAPrimitive."
<primitive: 105> super replaceFrom: start to: stop with:
replacement startingAt: repStart
This is what I did to see if the prim failed:
replaceFrom: start to: stop with: replacement startingAt: repStart
"Primitive. This destructively replaces elements from start to stop in
the receiver starting at index, repStart, in the collection,
replacement. Answer the receiver. Range checks are performed in the
primitive only. Optional. See Object documentation whatIsAPrimitive."
<primitive: 105> WOOPS ifNil: [ WOOPS _ #WOOPS.
self halt ]. super replaceFrom: start to: stop with: replacement
startingAt: repStart
And it did fail and I'm puzzled as to why:
