Bug ID: 51473
Summary: Clang user's Manual: need to explicitly state that
-pedantic does not warn on all language extensions
Product: clang
Version: 12.0
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: C

Clang user's manual: need to explicitly state that -pedantic does not warn on
all language extensions. In many cases when clang -pedantic compiles the code
containing extensions the diagnostics are missing. Hence, the end user assumes
that the situation around -pedantic is the same as in gcc: "This does not mean
that _all_ non-ISO constructs get warnings or errors". If this is indeed true,
then there is a need to explicitly state in clang user's manual
(https://clang.llvm.org/docs/UsersManual.html) that -pedantic does not warn on
all language extensions.
Text before:
-pedantic
Warn on language extensions.
Text after:
-pedantic
Warn on language extensions.
Caution: This does not mean that _all_ non-ISO C constructs get warnings.
Reason: detection of any failure to conform to ISO C is considered to not be
worth the effort required.
