[llvm-dev] External linkage functions which allocate memory

[raghesh via llvm-dev]

Hi All,

A correction in my query.

Please ignore this part --> "if any of the functions with external linkage
allocate memory". I think I have not used the term "external linkage"
promptly as per its definition.

What I would like to know is about the possibility of memory allocation by
those functions whose definitions are not there in the linked LLMV-IR.

Regards
Raghesh
