/*
|
|
All XASH_* macros set by this header are guaranteed to have positive value
|
|
otherwise not defined.
|
|
|
|
Every macro is intended to be the unified interface for buildsystems that lack
|
|
platform & CPU detection, and a neat quick way for checks in platform code
|
|
For Q_build* macros, refer to buildenums.h
|
|
|
|
Any new define must be undefined at first
|
|
You can generate #undef list below with this oneliner:
|
|
$ sed 's/\t//g' build.h | grep '^#define XASH' | awk '{ print $2 }' | \
|
|
sort | uniq | awk '{ print "#undef " $1 }'
|
|
|
|
Then you can use another oneliner to query all variables:
|
|
$ grep '^#undef XASH' build.h | awk '{ print $2 }'
