Bug ID: 23365
Summary: clang should not throw away #ident directives
Product: clang
Version: 3.5
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs

Classification: Unclassified
clang seems to throw away #ident directives without actually adding an
identification to the object file. #ident directives are useful for adding
version or copyright information to binaries and their usage is widespread
through the *BSD and Solaris code bases.
It would be great if clang could support #ident directives. The implementation
boils down to turning a directive in C or C++ source code of the form
#ident "something"
into assembly of the form
.ident "something"
on ELF targets at least, although the gas manual suggests that this directive
does something to a similar effect on other platforms as well. The general
mechanism to emit such assembly directives seems to exist already as clang is
able to emit a compiler identification string as an ident assembly directive.
