Hi,
I am trying to figure out the cause of a slow application startup, and the
evidence I have so far, points to mingw's _pei386_runtime_relocator()
routine as the culprit. When I start my app under debugger, I see this
function calling VirtualProtect() about a zillion times in a row.
Looking at
VirtualProtect() per relocation entry.
I am not entirely sure how this situation comes about, but here you go...

I've tried both patches (fixed conditions in Kai's) and both eliminate
extraneous calls to VirtualProtect. However Kai's patch did not seem to
affect startup performance at all. DW's patch, on the other hand, also
gets rid of VirtualQuery', and that cuts down the startup time of my test
example
Hi,
Is link-time dead code elimination via --function-sections +
-Wl,--gc-sections known to work on mingw?

Hi,
I think I am bumping into the issue described here:
https://sourceware.org/bugzilla/show_bug.cgi?id=16598. The bug also has a
patch attached. What would it take to get someone to merge it?
