Subject: [PATCH] cmake: Allow shared libraries to customize the soname using
|
||
|
|
LLVM_ABI_REVISION
|
||
|
|
|
||
|
|
The LLVM_ABI_REVISION variable is intended to be used for release
|
||
|
|
candidates which introduce an ABI change to a shared library. This
|
||
|
|
variable can be specified per library, so there is not one global value
|
||
|
|
for all of LLVM.
|
||
|
|
|
||
|
|
For example, if we LLVM X.0.0-rc2 introduces an ABI change for a library
|
||
|
|
compared with LLVM X.0.0-rc1, then the LLVM_ABI_REVISION number for
|
||
|
|
library will be incremented by 1.
|
||
|
|
|
||
|
|
In the main branch, LLVM_ABI_REVISION should always be 0, it is only
|
||
|
|
meant to be used in the release branch.

||
