## Introduction
|
|
|
|
This document contains the release notes for the Flang Fortran frontend,
|
|
part of the LLVM Compiler Infrastructure, release 15.0.0. Here we
|
|
describe the status of Flang in some detail, including major
|
|
improvements from the previous release and new feature work. For the
|
|
general LLVM release notes, see [the LLVM
|
|
documentation](https://llvm.org/docs/ReleaseNotes.html). All LLVM
|
|
releases may be downloaded from the [LLVM releases web
|
|
site](https://llvm.org/releases/).
|
|
|
|
Note that if you are reading this file from a Git checkout, this
|
|
document applies to the *next* release, not the current one. To see the
|
|
release notes for a specific release, please see the [releases

## Major New Features
|
|
|
|
## Bug Fixes
|
|
|
|
## Non-comprehensive list of changes in this release
|
|
* The bash wrapper script, `flang`, is renamed as `flang-to-external-fc`.
|
|
* In contrast to Clang, Flang will not default to using `-fpie` when linking
|
|
executables. This is only a temporary solution and the goal is to align with
|
|
Clang in the near future. First, however, the frontend driver needs to be
|
|
extended so that it can generate position independent code (that requires
|
|
adding support for e.g. `-fpic` and `-mrelocation-model` in `flang-new
|
|
-fc1`). Once that is available, support for the `-fpie` can officially be
|
|
added and the default behaviour updated.
|
|
|
|
## New Compiler Flags
|
|
* Refined how `-f{no-}color-diagnostics` is treated to better align with Clang.
|
|
In particular, both `-fcolor-diagnostics` and `-fno-color-diagnostics` are
|
|
now available in `flang-new` (the diagnostics are formatted by default). In
|
|
the frontend driver, `flang-new -fc1`, only `-fcolor-diagnostics` is
|
|
available (by default, the diagnostics are not formatted).
