Free Software I've Worked On

Ian Lance Taylor

I wrote a free UUCP package. It is known as Taylor UUCP or GNU UUCP. The current version is 1.07, released in June 2003. From here you can read a short description or the documentation, or you can download uucp-1.07.tar.gz.

I was the GNU Binutils maintainer from 1996 to 1999. I did a great deal of work on the binutils. Some of the larger items were:

• I rewrote the guts of the linker.
• I added support for parsing and converting debugging information.
• I added support for the PowerPC to the assembler and other tools, including support for XCOFF to the linker.
• I added SunOS shared library support, and worked extensively on ELF shared library support.
• I wrote the nlmconv and windres programs.

I have done a lot of work on the GNU Compiler Collection. I am currently a middle-end maintainer. Some specific work I've done:

• I brought the initial MIPS R4000 support into gcc, and I wrote the initial MIPS16 support.
• I was the fixincludes maintainer for a few years.
• I wrote the first version of the reload CSE pass.

I've contributed patches to a number of other free software packages, including:

• autoconf (I was one of the first beta testers, and added support for generating a header file).
• automake (I added support for conditionals).
• CVS (I added support for sending diffs across the network, and helped eliminate the last uses of RCS, among many other optimizations).
• GDB (many minor patches).
• Newlib (among other things, I wrote the single precision versions of the floating point routines, which were later picked up by several other libraries).
• RTEMS (I wrote the NE2000 driver).
• PostgreSQL (I added support for %TYPE to PL/pgSQL).
• Coreutils (I added support for tail -f on multiple files).

I wrote the initial version of the 64-bit PowerPC ELF ABI Supplement, which is used for 64-bit PowerPC Linux.
