Hello. I'm running the latest version of Valgrind from the Subversion tree, cross-compiled for ARM.
It compiled OK, and runs correctly on my ARM board, which is an Atmel AT91SAM9260 (an ARM926). I'm running the "arm-none-linux-gnueabi" cross-compilation tools from CodeSourcery, version 2008q3. All software compiled with this setup works on my ARM board, so I know it's not a problem with my cross-compilation setup. I had to change one thing in order to get it to compile: the "configure" script complained that my setting of the --host option wasn't a recognized architecture, because it tests for strings that look like "armv7*". So, I just changed "armv7*" to "arm*", to make it a little more liberal in what it accepts, and it worked. Valgrind runs on my ARM board, but unfortunately, upon encountering the very first instruction of a "Hello World" program, it aborts the program with SIGILL and prints the "Illegal opcode" error message. The various summary counts are correct, and the help screen also works just fine, so I know that it's not a problem starting up Valgrind itself. I tried "Hello World" again, compiled static (just to rule out a problem with a library). Running Valgrind on a known-good program, such as /bin/ls, also produces the same failure. Any idea on how I can troubleshoot this? Unfortunately, the opcodes that are supposedly illegal are not printed. I attempted to add a block to the error message handler, to print out the bytes at the address that was given, but ended up evidently getting the wrong area of memory instead (the bytes that appeared there did not match what was in the ".text" segment of the file, as shown by "objdump"). Is the ARM926's instruction set (ARMv5TEJ) supported? I'm not trying to use any exotic features of ARM, such as Thumb or NEON. Thanks!
