[fpc-devel] more question on -g commandline switches / -gv valgind

[Martin]

Trying to improve the lazarus user-interface for selecting what debug 
info to generate, I try to understand the relations between settings.
(as for example, indicating to the user, that -gl causes the same debug 
info than -g does)

Valgrind requires debug info too so -g-v is nonsnes.. It also understand 
stabs and dwarf, according to it's docs

The question is what does fpc do, if -gv is specified.

Does -gv :
- force either stabs or dwarf
- work with both, and add extend info (never mind if stabs or dwarf)
- observe stabs or dwarf setting (-gs / -gw) but only add info for one 
of the 2 formats?

In other words, does it make sense in Lazarus, to allow the user to 
choose explicit stab or dwarf; and then on top of that optionally add 
-gv ? Will it work as expected in any combination?
Or should lazarus, only allow stabs, or only dwarf, if the user gives -gv.
Or should Lazarus prevent the user from chosing stabs/dwarf at all, if 
-gv is selected? so it simply gives -g -gv (or  just -gv) to fpc, but 
NOT -gs / -gw ?
