4954,-eventlog / -debug should imply -rtsopts,duncan,,"The `-eventlog` flag links the program to the threaded rts. The eventlog is only generated when using the `-l` RTS flag, but by default we get
{{{
$ ./foo +RTS -l
Setup: Most RTS options are disabled. Link with -rtsopts to enable them.
}}}
You have to use both `-eventlog` and `-rtsopts` to be able to run with `+RTS -l`.

I think `-eventlog` should imply `-rtsopts` because it's pointless to use the `-eventlog` way if one never uses the runtime flag `+RTS -l`.

The `-rtsopts` was added as a security measure, so that by default the runtime `+RTS -RTS` options would not be available. Since `-eventlog` is a non-default option then I think it is also safe from a security POV to have it imply `-rtsopts`. 

For the security paranoid, at most, one could consider in the userguide where `-rtsopts` is mentioned and the security issue pointed out, that it could also mention what other flags imply `-rtsopts`.


BTW, I tried making a patch for this, but the `-eventlog` flag is a static flag while `-rtsopts` is a dynamic flag and it appears hard to make one imply the other (the only case where that is done is labeled as a hack).",feature request,closed,normal,7.4.1,Driver,7.0.1,fixed,,,Unknown/Multiple,Unknown/Multiple,None/Unknown,Unknown,,,,
