Valgrind with record-replay functionality

ValgrindRR

Make a record-replay debugging functionality into Valgrind 3.9.0.

We still consider make a Valgrind tool with RR-functionality or make patch to Valgrind core to let it support RR.

We want to use record-replay functionality with vgdb for debugging.

We are now doing the plan on valgrindrr_porting branch which is porting Mojiong's valgrindrr (for valgrind 3.3) to valgrind 3.9.

valgrindrr_porting branch

valgrindrr only support 32bits platform currently, but we can use it on 64bits linux to debug 32bits binary.

building step

• i386 linux:

  ./autogen.sh
  ./configure --prefix=`pwd`/inst
  make
  make install
  

• amd64 linux:

  ./autogen.sh
  ./configure --prefix=`pwd`/inst --build=i386-linux
  make
  make install
  

• ref: valgrind's build step: build valgrind tool

The executable is inst/bin/valgrind.

testing command

• record:

  valgrind --record-replay=1 --log-file-rr=<log_file> <exe> <exe_args>
  

<exe> and <exe_args> is client program we want to run on the valgrindrr.

• replay:

  valgrind --record-replay=2 --log-file-rr=<log_file>
  

testing scenario

RR functionality testing codes are in rr_testcode directory.

• bugs

  • #1 is for localtime_test.c, the part of /bin/date program
  • #2 is for file_IO.c.
