I am not talking about linux, and i am not talking about 3rd 
party tools

I am talking about the developers of DMD/LDC/GDC, do they profile 
the compilers, do they provide ways to monitor/track performance? 
do they benchmark specific parts of the compilers?

I am not talking about the output of valgrind

Zig also has: https://ziglang.org/perf/ (very slow to load)

Having such thing is more useful than being able to plug valgrind 
god knows how into the compiler and try to decipher what does 
what and what results correspond to what internally, and what 
about a graph over time to catch regressions?

DMD is very fast at compiling code, so i guess Walter doing 
enough work to monitor all of that

LDC on the other hand.. they'd benefit a lot by having such thing 
in place
