[flang][runtime] Let more list-directed child input advance (#160590)

Whether list-directed child READ statements should be allowed to advance
to further records is neither explicit in the standard nor consistent in
existing Fortran implementations. We allow child namelist READ
statements to advance, but not other list- directed child input.

This patch refines our interpretation of this case. Child namelist READ
statements continue to be able to advance; in addition, non-namelist
child READ statements can now advance if their parent READ statement is
a list-directed input statement at the top level, or a child that could.
But non-namelist list-directed child input taking place in a context
with explicit format control won't advance to following records, so that
the format-controlled parent READ statement can retain control over
record advancement.

Also corrects two cases of record repositioning in numeric input
editing, which were failing under child input because they weren't
allowing for left tab limits.

Fixes https://github.com/llvm/llvm-project/issues/160351.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM
