Source Edit

Conversions between literal ASTs (PNode) and VM memory. This is the boundary between the compiler and the VM: constants, macro arguments and static parameters are stored into VM memory, results of compile-time evaluation are loaded back into ASTs.

Imports

ast, types, options, msgs, lineinfos, int128, nimsets, bitsets, vmlayout, vmmem, astalgo

Types

ValueConv = object mem*: ptr VmMemory layouts*: ptr LayoutCache conf*: ConfigRef nilType*: PType ## the type of `nil`, for the C backend's sake: everything the conversions need; the VM context owns these. Source Edit

Procs

proc loadInt(src: Address; k: MemKind): BiggestInt {....raises: [], tags: [], forbids: [].}: loads a scalar and widens it to 64 bits, like the VM's registers do. Source Edit
proc loadValue(vc: ValueConv; src: Address; t: PType; info: TLineInfo): PNode {....raises: [ KeyError, OSError, Exception, ValueError, IOError, ERecoverableError], tags: [ ReadEnvEffect, ReadIOEffect, ReadDirEffect, RootEffect, WriteIOEffect], forbids: [].}: Reads the value of type t at src and turns it into a literal AST. Source Edit
proc storeValue(vc: ValueConv; dest: Address; n: PNode; t: PType; inConst: bool) {....raises: [ KeyError, OSError, Exception, ValueError, IOError, ERecoverableError], tags: [ ReadEnvEffect, ReadIOEffect, ReadDirEffect, RootEffect, WriteIOEffect], forbids: [].}: Source Edit
