Hi, Folks,
This is the beta release of gdb 4.17.0.6, which is based on gdb 4.17
plus Linux/x86 hardware watchpoint/FPU, glibc 2.0 pthread and Linux/PPC
support. You need linux 2.0.35 or above, or 2.1.xx to get the x86 FPU
to work correctly. The Linux/x86 binary works with all recent kernels
and C libraries, and the x86 FPU support is enabled at the run-time,
depending on the kernel version.
Please report any bugs related to gdb 4.17.0.6 to hjl@lucon.org.
Problems:
Because most of system calls in glibc 2 are written in assembly without
frame pointer, gdb may not be able to debug nor get stack trace system
calls on glibc-based 2 systems. Due to this, "make check" may fail in
FAIL: gdb.base/a1-selftest.exp: backtrace through signal handler
with glibc 2.
Also, it is normal to see
FAIL: gdb.base/interrupt.exp: continue (timeout)
FAIL: gdb.base/interrupt.exp: echo data (timeout)
if there is
XPASS: gdb.base/interrupt.exp: send_gdb end of file
Changes from gdb 4.17.0.5:
1. Support for glibc 2.0 pthread. It doesn't work with glibc 2.1.
2. The Linux/PPC support.
3. The Linux/Sparc support. Untested.
Changes from gdb 4.17.0.4:
1. Fix the Intel FPU tag code handling.
Changes from gdb 4.17.0.3:
1. Fix testcases for FPU.
2. Fix x86 hardware watchpoint support.
Changes from gdb 4.17.0.2:
1. Fake FP registers on older kernels.
Changes from gdb 4.17:
1. Linux/x86 FPU support is added. You can debug floating point numbers
just like integers.
2. x86 hardware watchpoint is extended to long long, double and long
double.
3. More information on x86 CPU status register.
4. Fix a bug when reading beyond the memory boundary.
