Re: [edk2-devel] [PATCH v6 1/7] MdeModulePkg: introduce PE/COFF image emulator protocol
Leif, How about using the following pragma instead if include guards? #pragma once https://en.wikipedia.org/wiki/Pragma_once This appears to be supports by GCC 3.4 and higher, clang, and VS. Might even speed up builds a bit.

Re: [edk2-devel] [PATCH v6 1/7] MdeModulePkg: introduce PE/COFF image emulator protocol
Hi Leif, This is not a macro that is to be used by C code. It is a technique to prevent recursive includes on a .h file. As a result, we do not want to use the C Coding Standard macro style. Are there other techniques to prevent recursive includes? I agree that macros/symbols that start with single or double '_' are reserved by compilers/linkers, which is why the warning is triggered and it would be better if we use a different technique. The current style assumes that the define symbol used will not collide with a compiler/linker symbol. The names are verbose, so the chances of a collision are very low.

Hmm... Not a major issue, but I'll mention it anyway (which I mentioned to Andrew/Mike at Linaro Connect in Vancouver last year): clang has a warning, enabled by -Wreserved-id-macro, which complains about this. The Coding Style matches this, suggesting MACROS_SHOULD_BE_WRITTEN_THUS_. So do we need to fix Ecc? Regards, Leif -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.

Hello Ard,
Sorry for the delayed response.
Could you help to use:
_PECOFF_IMAGE_EMULATOR_PROTOCOL_GUID_H_
here to please the Ecc checker when you push the series?
