Add x32 support to strace
X32 support is added to Linux kernel 3.4. In a nutshell, x32 is x86-64 with
32bit pointers. At system call level, x32 is also identical to x86-64,
as shown by many changes like "defined(X86_64) || defined(X32)". The
main differerence bewteen x32 and x86-64 is off_t in x32 is long long
instead of long.
This patch adds x32 support to strace. Tested on Linux/x32.
* configure.ac: Support X32.
* defs.h: Set SUPPORTED_PERSONALITIES to 3 for X86_64,
Set PERSONALITY2_WORDSIZE to 4 for X86_64.
Add tcb::ext_arg for X32.
* file.c (stat): New for X32.
(sys_lseek): Use 64-bit version for X32.
(printstat64): Check current_personality != 1 for X86_64.
* ipc.c (indirect_ipccall): Check current_personality == 1
for X86_64.
* mem.c (sys_mmap64): Also use tcp->u_arg for X32. Print NULL
for zero address. Call printllval for offset for X32.
* pathtrace.c (pathtrace_match): Don't check sys_old_mmap for
X32.
* process.c (ARG_FLAGS): Defined for X32.
(ARG_STACK): Likewise.

(change_syscall): Likewise.
(arg0_offset): Likewise.
(arg1_offset): Likewise.

Rewrite signal mask decoding without sigset_t
The sigset_t provided by libc is not quite convenient.
In glibc, sigset_t is an array with space for 1024 bits, which is much
more than required: all architectures supported by Linux have only 64
signals except MIPS, which has 128.
In bionic libc, LP32 sigset_t is only 4 bytes long, which is less than
necessary.
With this change, signal mask is decoded without use of intermediate
sigset_t structure, which saves us some cpu cycles in case of glibc with
its inflated sigset_t, and enables build with libcs where sigset_t is
broken.
Old implementation used to check each signal number in the given signal
mask twice using sigismember().
New implementation is based on popcount and next_set_bit() so it's
noticeably faster.
* configure.ac: Check for __builtin_popcount.
* signal.c: Ensure that NSIG >= 32.
(sprintsigmask, sprintsigmask_long, printsigmask): Remove.
(popcount32, sprintsigmask_n): New functions.
(tprintsigmask_addr, sprintsigmask_val, tprintsigmask_val): New macros.
(print_sigset_addr_len, sys_sigsetmask, sys_sigreturn, sys_siggetmask,
sys_sigsuspend, sys_sigprocmask, decode_new_sigaction): Update to use
new signal mask decoding interface.
* tests/sigaction.c (main): Add a test with almost filled signal mask.
* tests/sigaction.awk: Update.
