Topic created on: May 17, 2006 08:02 CDT by n4v4r4j .

i written a small program with some virtual functions..when i compiled it with MS VC++ compiler. I could able to see 'vftable' in the .text section in all M$ binaries (in their dll) but when i tried the same, with my small program 'vftable' is created in the .rdata section instead of .text section.

Is there anyway we could able to force the compiler to create 'vftable' in the .text section instead of .rdata section. I tried the same in the g++ too, but it creates
vftable in the .rdata section.

Do you know any compiler option in M$ v++ to force it ?

I think nowhere it is documented ...recent presentation about M$ binary too didnt give any clue about this !!

AFAIK, vftables are always placed into .rdata. The only way to get them into .text would be to merge it with .rdata with  the linker switch:
/merge:.rdata=.text

Be careful of section protection settings when merging .rdata with .text.
