10# generate a .def file
11#
12# It does this by parsing the header files and looking for the
13# prototyped functions: it then prunes the output.
14#
15# Intermediary files are created, call libcrypto.num and libssl.num,
16# The format of these files is:
17#
18# routine-name nnnn vers info
19#
20# The "nnnn" and "vers" fields are the numeric id and version for the symbol
21# respectively. The "info" part is actually a colon-separated string of fields
22# with the following meaning:
23#
24# existence:platform:kind:algorithms
25#
26# - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is
27# found somewhere in the source,
28# - "platforms" is empty if it exists on all platforms, otherwise it contains
29# comma-separated list of the platform, just as they are if the symbol exists
30# for those platforms, or prepended with a "!" if not. This helps resolve
31# symbol name variants for platforms where the names are too long for the
32# compiler or linker, or if the systems is case insensitive and there is a
33# clash, or the symbol is implemented differently (see
34# EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found
35# in the file crypto/symhacks.h.
36# The semantics for the platforms is that every item is checked against the
37# environment. For the negative items ("!FOO"), if any of them is false
38# (i.e. "FOO" is true) in the environment, the corresponding symbol can't be
39# used. For the positive items, if all of them are false in the environment,
40# the corresponding symbol can't be used. Any combination of positive and
41# negative items are possible, and of course leave room for some redundancy.
42# - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious.
43# - "algorithms" is a comma-separated list of algorithm names. This helps
44# exclude symbols that are part of an algorithm that some user wants to
45# exclude.

56# When building a "variant" shared library, with a custom SONAME, also customize
57# all the symbol versions. This produces a shared object that can coexist
58# without conflict in the same address space as a default build, or an object
59# with a different variant tag.
60#
61# For example, with a target definition that includes:
62#
63# shlib_variant => "-opt",
64#
65# we build the following objects:
66#
67# $ perl -le '
68# for (@ARGV) {
69# if ($l = readlink) {
70# printf "%s -> %s\n", $_, $l
71# } else {
72# print
73# }
74# }' *.so*
75# libcrypto-opt.so.1.1
76# libcrypto.so -> libcrypto-opt.so.1.1
77# libssl-opt.so.1.1
78# libssl.so -> libssl-opt.so.1.1
79#
80# whose SONAMEs and dependencies are:
81#
82# $ for l in *.so; do
83# echo $l
84# readelf -d $l | egrep 'SONAME|NEEDED.*(ssl|crypto)'
85# done
86# libcrypto.so
87# 0x000000000000000e (SONAME) Library soname: [libcrypto-opt.so.1.1]
88# libssl.so
89# 0x0000000000000001 (NEEDED) Shared library: [libcrypto-opt.so.1.1]
90# 0x000000000000000e (SONAME) Library soname: [libssl-opt.so.1.1]
91#
92# We case-fold the variant tag to upper case and replace all non-alnum
93# characters with "_". This yields the following symbol versions:
94#
95# $ nm libcrypto.so | grep -w A
96# 0000000000000000 A OPENSSL_OPT_1_1_0
