The code is indeed in the assembler file.

SymbolTable_GetVarPointerCheck
        .PROC
        .CALLINFO FRAME=128,CALLS,SAVE_RP,SAVE_SP,ENTRY_GR=3
        .ENTRY
        stw %r2,-20(%r30)
        copy %r3,%r1
        copy %r30,%r3
        stwm %r1,128(%r30)
        stw %r3,-4(%r30)
        stw %r26,-36(%r3)
        ldw -36(%r3),%r26
        .CALL ARGW0=GR
        [...]

However, the code did not seem to make it into the object file.

heap% nm FIO.o |grep FIO_OpenToRead
FIO_OpenToRead      |         0|extern|entry  |$CODE$

I do not understand this -- I clearly need to understand the build
process better.

(Sigh)
