7 | # Code in Makefile.am will invoke this script with two arguments. | |
8 | # The first is a GOARCH value. The second is a keyword. | |
9 | # The script will print the value of that keyword for that GOARCH. | |
10 | # Keywords: | |
11 | # - bigendian: true or false | |
12 | # - cachelinesize: the cache line size in bytes | |
13 | # (for performance only; it's not essential to get this right) | |
14 | # - defaultphyspagesize: the default physical page size in bytes | |
15 | # (not currently used, but maybe some day) | |
16 | # - family: the processor family, from ALLGOARCHFAMILY in configure.ac | |
ffad1c54 ILT |
17 | # - int64align: alignment of int64 type in bytes |
18 | # - maxalign: maximum alignment of values of Go types in bytes | |
19 | # - minframesize: size of smallest possible function frame in bytes | |
20 | # (not currently used, may never be used) | |
21 | # - pcquantum: minimum size of a single instruction in bytes | |
22 | # - ptrsize: size of a pointer in bytes | |
