In order to include the appropriate file a syscall_table.h is found via the perf include path and it includes the syscalls_32.h or syscalls_64.h as appropriate. To support having multiple syscall tables, one for 32-bit and one for 64-bit, or for different architectures, an include path cannot be used. Remove syscall_table.h because of this and inline what it does into syscalltbl.c. For architectures without a syscall_table.h this will cause a failure to include either syscalls_32.h or syscalls_64.h rather than a failure to include syscall_table.h. For architectures that only included one or other, the behavior matches BITS_PER_LONG as previously done on architectures supporting both syscalls_32.h and syscalls_64.h.

Errors-To: linux-riscv-bounces+linux-riscv=archiver.kernel.org@lists.infradead.org Identify struct syscall information in the syscalls table by a machine type and syscall number, not just system call number. Having the machine type means that 32-bit system calls can be differentiated from 64-bit ones on a machine capable of both. Having a table for all machine types and all system call numbers would be too large, so maintain a sorted array of system calls as they are encountered.

As there are gaps in the system call number there is a notion of index into the table. Going forward we want the system call table to be identifiable by a machine type, for example, i386 vs x86-64. Change the interface to the syscalltbl so (1) a (currently unused machine type of EM_HOST) is passed (2) the index to syscall number and system call name mapping is computed at build time. Two tables are used for this, an array of system call number to name, an array of system call numbers sorted by the system call name. The sorted array doesn't store strings in part to save memory and relocations. The index notion is carried forward and is an index into the sorted array of system call numbers, the data structures are opaque (held only in syscalltbl.c), and so the number of indices for a machine type is exposed as a new API. The arrays are computed in the syscalltbl.sh script and so no start-up time computation and storage is necessary.

For kernel types assume the e_machine matches the perf tool. In other cases return EM_NONE. When reading from the ELF header use DSO__SWAP that may need dso->needs_swap initializing. Factor out dso__swap_init to allow this.

If live use the executable from /proc/pid/exe and read the e_machine from the ELF header. On failure use EM_HOST. Change builtin-trace syscall functions to pass e_machine from the thread rather than EM_HOST, so that in later patches when syscalltbl can use the e_machine the system calls are specific to the architecture.

In a syscalltbls array have references to each architectures tables along with the corresponding e_machine. When the 32-bit or 64-bit table is ambiguous, match the perf binary's type. For ARM32 don't use the arm64 32-bit table which is smaller. EM_NONE is present for is no machine matches. Conditionally compile the tables, only having the appropriate 32 and 64-bit table. If ALL_SYSCALLTBL is defined all tables can be compiled.
