主题: 答复: Please check the dhat could run in the ELF32 mode in x86-64.
Hi, there are some progress I analyzed.
1: If function main is empty, it also failed. The code as below.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <fcntl.h>
#include <unistd.h>
#include <sys/mman.h>
#include <sys/types.h>
#include <sys/stat.h>
int main(int argc, char *argv[])
{
Return 0;
}
The compile cmd: gcc -g -O0 -m32 main.c
2: This static void final_tidyup(ThreadId tid) send the Vg_CoreClientReq cmd,
and dh_handle_noninsn_write go the default branch. But In x86_64 mode, it
never go the default branch.
It is very urgent now. Can you show me how to resolve it .

Hi: I compile the code in x86-64 machine, and run dhat . it is ok.
The compile cmd: gcc -g -O0 main.c
The dhat cmd valgrind �Ctool=exp-dhat ./a.out
But I compile the same code in the same machine, but another compile cmd, and
run dhat. It failed.
The compile cmd: gcc -g -O0 -m32 main.c
The dhat cmd valgrind �Ctool=exp-dhat ./a.out
I just compile same code into ELF32 mode.
The output as below:
DHAT: dh_main.c:756 (dh_handle_noninsn_write): the 'impossible' happened.
