Subject: [WebAssembly] Define a custom segment type for function definitions.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=3a52c6e4b7ba49898b1700f3c39fc2f7b7913746;p=oota-llvm.git

[WebAssembly] Define a custom segment type for function definitions.

Since function definitions are not loaded into the address space, PT_LOAD is
inappropriate. PT_WEBASSEMBLY_FUNCTIONS is used to identify where the function
definitions are so that they can be processed at program startup time.
