#2234: Profiled binaries create empty files +--- Reporter: guest| Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 6.8.2|Severity: minor Keywords: |Testcase: Architecture: Unknown | Os: Unknown +--- [EMAIL PROTECTED]:1891~ghc --version [ 1:20PM] The Glorious Glasgow Haskell Compilation System, version 6.8.2 I recently happened to go through the effort to build a copy of Darcs with profiling enabled (to profile, obviously), and while the profiling runs were quite as helpful as I could've wished, I've since noticed something very annoying: [EMAIL PROTECTED]:1922~~/bin/bin/darcs whatsnew [ 1:35PM] No changes! [EMAIL PROTECTED]:1923~cat darcs.prof [ 1:36PM] [EMAIL PROTECTED]:1924~ls [ 1:36PM] bin/ _darcs/ darcs.prof hacryptopp/ hiersort/ hope/ idris/ ivor/ par-gc-ismm08.pdf pics2/ torrent/ Note the complete lack of any +RTS-RTS flags; nevertheless, an annoying empty file has been created to clutter up my home directory. And deleting it is pointless since it'll just get created. Even worse, this stupid file will appear anywhere I use the profiled darcs (at last count, slocate knew of at least 12 such darcs.prof). And since my system is set up for profiling, it'll only get worse as more and more binaries get built for profiling. I understand from Igloo there's some vague user-friendliness rationale behind GHC's littering, but I'm skeptical that this is really the best way to go about matters. -- gwern -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/2234 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

Comment (by wolfgang):
Yes, my code was wrong.
I think your code still leaves out most corner cases:
Consider 0x0001, or 0x8000.
If the high word is 0 of -1 , and the sign bit of the low word matches
that, THEN one word is enough.
So I would recommend the following (untested):
{{{
if ( (hi == 0 %ge( lo, 0 )) || (hi == 0x %lt(lo,
0) ) {
words_needed = 1;
// minimum is one word
} else {
words_needed = 2;
}
}}}
