[question/feature request] Expand macros in coverage reports #11

Closed chpio closed 5 years ago

chpio commented 7 years ago

Hi,

my code consists pretty much of macros which makes the reports pointless. Is there an option (i looked at the help page & couldn't find anything) or some thing to enable macro expansions in the reports?

kcov gets line information from the DWARF symbol, which only contains the line information where the macro is invoked. See https://github.com/rust-lang/rust/issues/39153.

Maybe you could try build with the environment variable RUSTFLAGS=-Zdebug-macros, as mentioned in that comment, to see if the result is better?
