C++ (Cpp) Location Examples

Example #1

File: region-selection.cpp Project: DREVILSWATERBOY/hhvm

std::string show(RegionDesc::Location l) {
  switch (l.tag()) {
  case RegionDesc::Location::Tag::Local:
    return folly::format("Local{{{}}}", l.localId()).str();
  case RegionDesc::Location::Tag::Stack:
    return folly::format("Stack{{{}}}", l.offsetFromFP().offset).str();
  }
  not_reached();
}

Example #2

File: irgen-guards.cpp Project: LouisRenWeiWei/hhvm

void assertTypeLocation(IRGS& env, const RegionDesc::Location& loc, Type type) {
  assertx(type <= TStkElem);
  using T = RegionDesc::Location::Tag;
  switch (loc.tag()) {
  case T::Stack:
    assertTypeStack(env, offsetFromBCSP(env, loc.offsetFromFP()), type);
    break;
  case T::Local:
    assertTypeLocal(env, loc.localId(), type);
    break;
  }
}

Example #3

File: irgen-guards.cpp Project: LouisRenWeiWei/hhvm

void predictTypeLocation(
  IRGS& env,
  const RegionDesc::Location& loc,
  Type type
) {
  using T = RegionDesc::Location::Tag;
  switch (loc.tag()) {
  case T::Stack:
    predictTypeStack(env, offsetFromBCSP(env, loc.offsetFromFP()), type);
    break;
  case T::Local:
    predictTypeLocal(env, loc.localId(), type);
    break;
  }
}

Example #4

File: irgen-guards.cpp Project: LouisRenWeiWei/hhvm

                       const RegionDesc::Location& loc,
                       Type type,
                       Offset dest,
                       bool outerOnly) {
