Bug ID: 35705
Summary: Kaleidoscope Source Chapter 8 Does not Compile
Product: Documentation
Version: 5.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: General docs
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
The tutorial available here: https://llvm.org/docs/tutorial/LangImpl08.html
Provides source code for the Kaleidoscope compiler, that does not compile, due
to the following two cases, where it appears that the provided source is out of
date compared to the llvm API.
Case 1:
-------
toy.cpp:1440:25: error: cannot initialize a parameter of type 'llvm::DIFile *'
with an lvalue of type 'const char [7]'
dwarf::DW_LANG_C, "fib.ks", ".", "Kaleidoscope Compiler", 0, "", 0);
Due to: https://reviews.llvm.org/D27762
KSDbgInfo.TheCU = DBuilder->createCompileUnit(dwarf::DW_LANG_C,
"fib.ks", ".", "Kaleidoscope Compiler", 0, "",
0);
Possibly this should be:
KSDbgInfo.TheCU = DBuilder->createCompileUnit(dwarf::DW_LANG_C,
DBuilder->createFile("fib.ks", "."),
"Kaleidoscope Compiler", 0, "", 0);
Case 2:
--------
toy.cpp:826:55: error: too many arguments to function call, expected 3, have 4
DblTy = DBuilder->createBasicType("double", 64, 64, dwarf::DW_ATE_float);
Possibly this should be:
DblTy = DBuilder->createBasicType("double", 64, dwarf::DW_ATE_float);
Request that the source code in the documentation be updated. Note that
similiar source code appears on multiple pages under
https://llvm.org/docs/tutorial/
