I've been using the nifty: DEBUG(errs() << "Here is the state of things:\n"); style of optional logging, but ran into an issue where I want to dump a table of information. The problem is getting the columns to line up, since the raw_ostream methods write numbers as variable length. I've worked up a patch that adds two new methods to raw_ostream: /// write_hex - Output \arg N as ten char hexadecimal string, including /// 0x prefix (e.g. 0x12345678 or 0x00000001). raw_ostream &write_hex32(uint32_t N); /// write_hex - Ou...

Hi Craig, I updated from the trunk some minutes ago, and thus got the "explicit". PrintReg constructor. When I do not include raw_ostream.h after including Debug.h in the backend cpp files, I now get compilation errors, not only when trying to print floats but also in other places. For example, for the code bool ADRESRegisterInfo::hasReservedCallFrame(const MachineFunction &MF) const { dbgs() << "hasReservedCallFr...

...39;t albeit in a very old master. No, I meant I didn’t see the race in the code you showed for the operator<<().

This code from raw_ostream.h is really racy: raw_ostream &operator<<(StringRef Str) { // Inline fast path, particularly for strings with a known length. size_t Size = Str.size(); // Make sure we can use the fast path. if (Size > (size_t)(OutBufEnd - OutBufCur)) return write(Str.data(),...

Could you dig into why: + raw_ostream &write(unsigned char C) override { + grow(1); + *OutBufCur++ = C; + return *this; + } Is 3 times as fast as raw_svector_ostream? I don't see a good reason why that should be any faster than: raw_ostream &operator<<(char C) { if (OutBufCur >= OutBufEnd) r...
