-Godefs is a bootstrapping tool for porting the Go runtime to new systems.
-It translates C type declarations into C or Go type declarations
-with the same memory layout.
-
-Usage: godefs [-g package] [-c cc] [-f cc-arg]... [defs.c ...]
-
-Godefs takes as input a host-compilable C file that includes
-standard system headers. From that input file, it generates
-a standalone (no #includes) C or Go file containing equivalent
-definitions.
-
-The input to godefs is a C input file that can be compiled by
-the host system's standard C compiler (typically gcc).
-This file is expected to define new types and enumerated constants
-whose names begin with $ (a legal identifier character in gcc).
-Godefs compile the given input file with the host compiler and
-then parses the debug info embedded in the assembly output.
-This is far easier than reading system headers on most machines.
-
-The output from godefs is either C output intended for the
-Plan 9 C compiler tool chain (6c, 8c, or 5c) or Go output.
-
-The options are:
-
- -g package
- generate Go output using the given package name.
- In the Go output, struct fields have leading xx_ prefixes
- removed and the first character capitalized (exported).
-
- -c cc
- set the name of the host system's C compiler (default "gcc")
-
- -f cc-arg
- add cc-arg to the command line when invoking the system C compiler
- (for example, -f -m64 to invoke gcc -m64).
- Repeating this option adds multiple flags to the command line.
-
-For example, if this is x.c:
-
- #include <sys/stat.h>
-
- typedef struct timespec $Timespec;
- enum {
- $S_IFMT = S_IFMT,
- $S_IFIFO = S_IFIFO,
- $S_IFCHR = S_IFCHR,
- };
-
-then "godefs x.c" generates:
-
- // godefs x.c
- // MACHINE GENERATED - DO NOT EDIT.
-
- // Constants
- enum {
- S_IFMT = 0xf000,
- S_IFIFO = 0x1000,
- S_IFCHR = 0x2000,
- };
-
- // Types
- #pragma pack on
-
- typedef struct Timespec Timespec;
- struct Timespec {
- int64 tv_sec;
- int64 tv_nsec;
- };
- #pragma pack off
-
-and "godefs -g MyPackage x.c" generates:
-
- // godefs -g MyPackage x.c
- // MACHINE GENERATED - DO NOT EDIT.
-
- package MyPackage
-
- // Constants
- const (
- S_IFMT = 0xf000;
- S_IFIFO = 0x1000;
- S_IFCHR = 0x2000;
- )
-
- // Types
-
- type Timespec struct {
- Sec int64;
- Nsec int64;
- }
