Subject: [PATCH] Fix build with GCC 14 on ARM (#78704)
|
|
|
|
GCC 14 defines `__arm_streaming` as a macro expanding to
|
|
`[[arm::streaming]]`. Due to the nested macro use, this gets expanded
|
|
prior to concatenation.
|
|
|
|
It doesn't look like C++ has a really clean way to prevent macro
|
|
expansion. The best I have found is to use `EMPTY ## X` where `EMPTY` is
|
|
an empty macro argument, so this is the hack I'm implementing here.
|
|
|
|
Fixes https://github.com/llvm/llvm-project/issues/78691.
