Proposed patch
Hi Pali,
Please try out this patch and let me know if it works for you.
I must admit that for the longest time I was blaming the lto plugin
rather than the linker, but it turns out that I was wrong. The key
fact is that if the user adds "-e <foo>" to the linker command line
then code in ld/ldemul.c adds an unresolved reference to <foo> which
in turn prevents the LTO compiler from optimizing away any definitions
of <foo>. When -e is not used, this undefined reference (to the default
startup symbol _mainCRTStartup) was not being created and so the LTO
compiler was dropping the code...
Cheers
Nick
