BTW, forgot to version this correctly. Current patch is v4. For those interested, here's a link to the previous version: http://marc.info/?l=strace&m=139170929111223&w=2 This v4 patch had to be completely re-written, for two reasons. First, the Nios-II Linux port landed in mainline and now uses the generic syscall ABI. And also, strace arch-specific code was re-organized. The diffstat speaks for itself about the advantages of using the generic syscall ABI and the impact of the strace cleanup (consider v3 had roughly 500 insertions!). Finally, here's a tiny example of strace running Nios-II: # strace ls execve("/bin/ls", ["ls"], [/* 16 vars */]) = 0 brk(0) = 0xb9000 uname({sysname="Linux", nodename="buildroot", ...}) = 0 faccessat(AT_FDCWD, "/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=64, ...}) = 0 mmap2(NULL, 64, PROT_READ, MAP_PRIVATE, 3, 0) = 0x2aac8000 close(3) = 0 openat(AT_FDCWD, "/lib/tls/libc.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) fstatat64(AT_FDCWD, "/lib/tls", 0x7fb43588, 0) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "/lib/libc.so.6", O_RDONLY|O_CLOEXEC) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0q\0\1\0\0\0\274l\2\0004\0\0\0"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=1438528, ...}) = 0 mmap2(NULL, 1445956, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0x2aac9000 mmap2(0x2ac14000, 81920, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x14a000) = 0x2ac14000 mmap2(0x2ac28000, 8260, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x2ac28000 close(3) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ac2b000 mprotect(0x2ac14000, 61440, PROT_READ) = 0 mprotect(0x2aac5000, 4096, PROT_READ) = 0 munmap(0x2aac8000, 64) = 0 getuid() = 0 gettimeofday({1167609616, 759566}, NULL) = 0 ioctl(0, TIOCGWINSZ, {ws_row=0, ws_col=0, ws_xpixel=0, ws_ypixel=0}) = 0 ioctl(1, TCGETS, {B115200 opost isig icanon echo ...}) = 0 ioctl(1, TCGETS, {B115200 opost isig icanon echo ...}) = 0 brk(0) = 0xb9000 brk(0xda000) = 0xda000 fstatat64(AT_FDCWD, ".", {st_mode=S_IFDIR|0700, st_size=0, ...}, 0) = 0 openat(AT_FDCWD, ".", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 3 getdents64(3, /* 6 entries */, 32768) = 192 getdents64(3, /* 0 entries */, 32768) = 0 close(3) = 0 exit_group(0) = ? +++ exited with 0 +++ Enjoy! -- Ezequiel Garcia, VanguardiaSur www.vanguardiasur.com.ar ------------------------------------------------------------------------------ BPM Camp - Free Virtual Workshop May 6th at 10am PDT/1PM EDT Develop your own process in accordance with the BPMN 2 standard Learn Process modeling best practices with Bonita BPM through live exercises http://www.bonitasoft.com/be-part-of-it/events/bpm-camp-virtual- event?utm_ source=Sourceforge_BPM_Camp_5_6_15&utm_medium=email&utm_campaign=VA_SF _______________________________________________ Strace-devel mailing list Strace-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/strace-devel
