Paolo Bonzini	a05b986d74	rust: trace: libc does not have syslog on windows Reported-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	7 months ago
Paolo Bonzini	3d508e096b	tracetool: add Rust DTrace/SystemTap SDT support Implement DTrace/SystemTap SDT by emitting the following: - The probe crate's probe!() macro is used to emit a DTrace/SystemTap SDT probe. - Every trace event gets a corresponding trace_<name>_enabled() -> bool generated function that Rust code can use to avoid expensive computation when a trace event is disabled. This API works for other trace backends too. `#[allow(dead_code)]` additions are necessary for QEMU's dstate in generated trace-<dir>.rs files since they are unused by the dtrace backend. `./configure --enable-trace-backends=` can enable multiple backends, so keep it simple and just silence the warning instead of trying to detect the condition when generating the dstate code can be skipped. The tracetool tests are updated. Take a look at tests/tracetool/dtrace.rs to see what the new generated code looks like.

Tanish Desai	1461752f0f	tracetool/syslog: add Rust support The syslog backend needs the syslog function from libc and the LOG_INFO enum value; they are re-exported as "::trace::syslog" and "::trace::LOG_INFO" so that device crates do not all have to add the libc dependency, but otherwise there is nothing special.

Tanish Desai	54140102d2	rust: add trace crate The trace crate is a minimal container for dependencies of tracepoints (so that they do not have to be imported in all the crates that use tracepoints); it also contains a macro called "include_trace!" that is able to find the right include file from the trace/ directory.
