[PATCH] Simplify integer output-related functions in libgfortran

Merry Christmas! The code related to integer output in libgfortran has accumulated some… oddities over the years. I will soon post a finalized patch for faster integer-to-decimal conversion (see https://gcc.gnu.org/pipermail/fortran/2021-December/057201.html), but while working on that I found

[PATCH] Make integer output faster in libgfortran

Hi, Integer output in libgfortran is done by passing values as the largest integer type available. This is what our gfc_itoa() function for conversion to decimal form uses, as well, performing series of divisions by 10. On targets with a 128-bit integer type (which is most targets, really, nowa

Re: [PATCH] Simplify integer output-related functions in libgfortran

First merry Christmas to all! Bootstrapped and regtested on x86_64-pc-linux-gnu. OK to commit? OK. Thanks for the (preliminary) patch!

Re: [PATCH] Make integer output faster in libgfortran

Hi FX, The patch has been bootstrapped and regtested on two 64-bit targets: aarch64-apple-darwin21 (development branch) and x86_64-pc-gnu-linux. I would like it to be tested on a 32-bit target without 128-bit integer type. Does someone have access to that? There are two possibilities: Eithe

Re: [PATCH] Make integer output faster in libgfortran

Hi fX, right now I don’t have a Linux system with 32-bit support. I’ll see how I can connect to gcc45, but if someone who is already set up to do can fire a quick regtest, that would be great;) I tested this on x86_64-pc-linux-gnu with make -k -j8 check-fortran RUNTESTFLAGS="--target_board=
