Summary: Kaleidoscope (toy-v3) does optimise, doc-text say not.
Unclear!
Product: Documentation
Version: 2.6
Platform: Macintosh
URL: http://llvm.org/releases/2.6/docs/tutorial/LangImpl3.htm
l#driver
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: General docs
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
This section, about code-generation say the code is not optimized. (will be
added in next chapter)
As an example the code for '4+5;' is given which should (by the text) result in
an add instruction.
Compling that code (with release 2.6) shows different, however. The shown code
is optimized; it becomes the value 9.0
Log:
|| ready> 4+5;
|| ready> Read top-level expression:
|| define double @2() {
|| entry:
|| ret double 9.000000e+00
|| }
Hope this helps --Albert
