[LLVMdev] LLD input graph handling proposal
...erence is passing back info to the InputGraph as a parameter in nextFile() vs as a separate method call. My original draft email had a parameter in nextFile(), but it seemed a little confusing because the information was referring to the previous file. That is, if the current resolver state has newDefinedAtoms, that really means the last file (returned by nextFile()) caused new atoms to be added. In your ResolverState you have bits for all the kinds of atoms added. Is all that needed? I think all the InputGraph needs to know is if the last file was used. A group is scanned repeatedly until there i...

Hi Nick, Read this along with this example extract: ld -flavor gnu main.o thread.o --start-group libc.a libpthread.a --end-group function.o main.o has atoms ------------------------ main (defined) printf(undefined) fn(undefined) thread.o has atoms ----------------------------- pthread_create (undefined) libc.a(printf.o) has atoms ------------------------------------ printf(defined)

[LLVMdev] LLD input graph handling proposal
Shankar and I discussed input file handling, and we came up with a design that may greatly simplify the input file handling, while giving more flexibility to developer to support complicated options, such as --{start,end}-group, -z rescan or -z rescan-now. It'd worth pursuing, so here's the idea: 1. We wouldn't probably want to let Resolver to handle the input graph directly, for we
