Bug ID: 50040
Summary: Bogus semantic errors from
BuildRuntimeDerivedTypeTables
Product: flang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected],

Fortran::semantics::BuildRuntimeDerivedTypeTables generates bogus semantic
errors. Currently none of the Flang drivers reports them (e.g. via
`semantics.EmitMessages(llvm::errs())`), so this is unnoticed for the end
users. However, this also means that potentially valid semantic errors reported
by BuildRuntimeDerivedTypeTables are ignored. Please see
https://reviews.llvm.org/D100648 for more context and a reproducer.
This affects 4 regression tests:
* flang/test/Semantics/data05.f90
* flang/test/Semantics/offsets01.f90
* flang/test/Semantics/offsets02.f90
* flang/test/Semantics/typeinfo01.f90
Tested with ToT llvm-project: 24185541ca48bd7ed089a4dbf57bdcb91e290508
