1 /* log-for-trace.h: logging basics required by the trace.h generated
2 * by the log trace backend.
3 *
4 * This should not be included directly by any .c file: if you
5 * need to use the logging functions include "qemu/log.h".
6 *
7 * The purpose of splitting these parts out into their own header
8 * is to catch the easy mistake where a .c file includes trace.h
9 * but forgets to include qemu/log.h. Without this split, that
10 * would result in the .c file compiling fine when the default
11 * trace backend is in use but failing to compile with any other
12 * backend.
