In the meantime, I made a patch for gdb 4.17 to support FPU on Linux/x86. Here is the ChangeLog. The source code patch and linux/x86 binaries are available at ftp://ftp.yggdrasil.com/private/hjl/gdb-4.17.linux.diff.gz ftp://ftp.yggdrasil.com/private/hjl/gdb-4.17.fpu.x86.bz2 I'd like to hear results on libc 5/linux 2.0.3x, libc 5/linux 2.1.xx, glibc 2.0.x/linux 2.0.3x and glibc 2.0.x/linux 2.1.xx.
