timberc's Introduction
======================================= Welcome to the Timber compiler sources! ======================================= Requirements ============ To compile the Timber compiler, you'll need ghc (haskell.org/ghc) gcc (gcc.gnu.org) Furthermore, to compile the grammar (Parser.y into Parser.hs) you'll need happy (haskell.org/happy) Version numbers known to work are ghc 6.10.1, happy 1.17, and gcc 4.0. Installing ============= If you have the cabal-install package installed, the following works: cabal install timberc If you would rather do a manual installation of the compiler in the default location (you may need root privileges for this), use the following commands: runhaskell Setup.lhs configure runhaskell Setup.lhs build runhaskell Setup.lhs install You can select another location for the installation of the compiler by using the following commands: runhaskell Setup.lhs configure --user --prefix=<the install path> runhaskell Setup.lhs build runhaskell Setup.lhs install You can also give other options to the installation script, see runhaskell Setup.lhs configure --help. Running ======= For info on how to run the compiler once installed, type timberc --help Reporting bugs ============== Please use the Trac system at http://trac.haskell.org/timber/ Further information =================== Please visit http://timber-lang.org

Function call used instead of primitive arithmetic operation
What steps will reproduce the problem?
compile a module with content
module A where
g :: Int -> Int
g x = x * 5
inspecting produced file A.c
Int f_A (Int x_2) {
return _sym_622_Prelude/* * */(x_2, 5);
}
compile a second module
module B where
f :: Int -> Int
f x = x * 5
g :: Int -> Int
g x = f (x +1)
inspecting the produced file B.c
Int f_B (Int x_3) {
return _sym_622_Prelude/* * */(x_3, 5);
}
Int g_B (Int x_4) {
return ((x_4 + 1) * 5);
}
What is the expected output? What do you see instead?
primitive integer multiplication is used in the second module but not in the
first.
What version of the product are you using? On what operating system?
