-Subject: [PATCH 1/3] lib/crc32.c: mark crc32_le_base/__crc32c_le_base aliases
- as __pure
-Date: Sat, 9 Feb 2019 01:08:38 +0100

-
-The upcoming GCC 9 release extends the -Wmissing-attributes warnings
-(enabled by -Wall) to C and aliases: it warns when particular function
-attributes are missing in the aliases but not in their target.
-
-In particular, it triggers here because crc32_le_base/__crc32c_le_base
-aren't __pure while their target crc32_le/__crc32c_le are.
-
-These aliases are used by architectures as a fallback in accelerated
-versions of CRC32. See commit 9784d82db3eb ("lib/crc32: make core crc32()
-routines weak so they can be overridden").
-
-Therefore, being fallbacks, it is likely that even if the aliases
-were called from C, there wouldn't be any optimizations possible.
-Currently, the only user is arm64, which calls this from asm.
-
-Still, marking the aliases as __pure makes sense and is a good idea
-for documentation purposes and possible future optimizations,
-which also silences the warning.

-From the GCC manual:
-
- copy
- copy(function)
-
- The copy attribute applies the set of attributes with which function
- has been declared to the declaration of the function to which
- the attribute is applied. The attribute is designed for libraries
- that define aliases or function resolvers that are expected
- to specify the same set of attributes as their targets. The copy
- attribute can be used with functions, variables, or types. However,
- the kind of symbol to which the attribute is applied (either
- function or variable) must match the kind of symbol to which
- the argument refers. The copy attribute copies only syntactic and
- semantic attributes but not attributes that affect a symbol’s
- linkage or visibility such as alias, visibility, or weak.
- The deprecated attribute is also not copied.
-
- https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html
-
-The upcoming GCC 9 release extends the -Wmissing-attributes warnings
-(enabled by -Wall) to C and aliases: it warns when particular function
-attributes are missing in the aliases but not in their target, e.g.:
-
- void __cold f(void) {}
- void __alias("f") g(void);
-
-diagnoses:
-
- warning: 'g' specifies less restrictive attribute than
- its target 'f': 'cold' [-Wmissing-attributes]
-
-Using __copy(f) we can copy the __cold attribute from f to g:
-
- void __cold f(void) {}
- void __copy(f) __alias("f") g(void);
-
-This attribute is most useful to deal with situations where an alias
-is declared but we don't know the exact attributes the target has.
-
-For instance, in the kernel, the widely used module_init/exit macros
-define the init/cleanup_module aliases, but those cannot be marked
-always as __init/__exit since they some modules do not have their
-functions marked as such.

-
-The upcoming GCC 9 release extends the -Wmissing-attributes warnings
-(enabled by -Wall) to C and aliases: it warns when particular function
-attributes are missing in the aliases but not in their target.
-
-In particular, it triggers for all the init/cleanup_module
-aliases in the kernel (defined by the module_init/exit macros),
-ending up being very noisy.
-
-These aliases point to the __init/__exit functions of a module,
-which are defined as __cold (among other attributes). However,
-the aliases themselves do not have the __cold attribute.
-
-Since the compiler behaves differently when compiling a __cold
-function as well as when compiling paths leading to calls
-to __cold functions, the warning is trying to point out
-the possibly-forgotten attribute in the alias.
-
-In order to keep the warning enabled, we decided to silence
-this case. Ideally, we would mark the aliases directly
-as __init/__exit. However, there are currently around 132 modules
-in the kernel which are missing __init/__exit in their init/cleanup
-functions (either because they are missing, or for other reasons,
-e.g. the functions being called from somewhere else); and
-a section mismatch is a hard error.
-
-A conservative alternative was to mark the aliases as __cold only.
-However, since we would like to eventually enforce __init/__exit
-to be always marked, we chose to use the new __copy function
-attribute (introduced by GCC 9 as well to deal with this).
-With it, we copy the attributes used by the target functions
-into the aliases. This way, functions that were not marked
-as __init/__exit won't have their aliases marked either,
-and therefore there won't be a section mismatch.
-
-Note that the warning would go away marking either the extern
-declaration, the definition, or both. However, we only mark
-the definition of the alias, since we do not want callers
-(which only see the declaration) to be compiled as if the function
-was __cold (and therefore the paths leading to those calls
-would be assumed to be unlikely).
