Generic tracer 0.4

Author: modest

# Views: 4690

New version is out.

changelog:

* FPU registers support at BPX breakpoint
new command line options:
-fpu_always - always show FPU registers at BPX breakpoint
-fpu_never - never show FPU registers at BPX breakpoint
In SET option of BPX command now it is possible to use FPU registers:
ST0..ST7, for example:
bpx=program.exe!address,set(st0,123.4)
Remember: gt never modify FPU tag word registor as well as not modify
TOP register, so, if some register was marked as "empty" and gt set
some value there, it will remain marked "empty".
if the float-point number is also NaN, MMX register contents will be
dumped too
new command line option:
-dump_xmm - dump XMM registers state at BPX breakpoint
* now we attach to all processes with process name specified
* symbol defined in address can also contain "+ofs" suffix, where
"ofs" is decimal or hexadecimal number with "0x" prefix
for example: "bpx=kernel32.dll!writefile+0x5" or "bpx=file.exe!base
+0x1234" where base is PE file base.
* PDB files support.
compile your program with /Zi option in MSVC and get PDB debug file
for it
