| | | | | | | | | | | | | | | | | | The definition of ntohs comes from user space include headers netinet/in.h which could define it as function instead of macro. So use builtin kernel be16_to_cpu instead. * tapset/aux_syscalls.stp (_struct_sockaddr_u): Define and use _stp_ntohs as be16_to_cpu.

| | | | | | | | | | | | | | | | | | | | | | | | Allocated section needs to be writable when creating pic shared objects because we store relocatable addresses in them. * includes/sys/sdt.h (ALLOCSEC): New macro, depends on __PIC__. (STAP_PROBE_DATA_): Use new ALLOCSEC macro.
| | * Remove the filename copy from token->locationJosh Stone2009-07-094-37/+30
| | | | | | | | | | | | | | | The location already has a pointer to a stapfile with the filename, so there's no need to keep an extra copy.
| | * Optimize string usage in the lexerJosh Stone2009-07-092-113/+101
| | | | | | | | | | | | | | | This speeds up the parsing stage >2x, mostly by minimizing string construction and comparison where char comparison will do.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will first read in the symbol table for modules, and update the dwarf cu_function_cache with aliased names too.
