Merge branch 'anders/diameter/make/OTP-9638'
* anders/diameter/make/OTP-9638: Dumb down release target to Solaris /usr/ucb/install Dumb down opt/release targets to make 3.80 Minor tweaks and cleanup Need absolute -pa for bootstrap build Simpler release targets for src subdirectories Use secondary expansion for src subdirectory rules One makefile for src build instead of recursion Remove app dependency on compiler to avoid forced recompilation Move diameter_exprecs to compiler directory

+%%
+%% Parse transform for generating record access functions
+%%
+%% This parse transform can be used to reduce compile-time
+%% dependencies in large systems.
+%%
+%% In the old days, before records, Erlang programmers often wrote
+%% access functions for tuple data. This was tedious and error-prone.
+%% The record syntax made this easier, but since records were implemented
+%% fully in the pre-processor, a nasty compile-time dependency was
+%% introduced.
+%%
+%% This module automates the generation of access functions for
+%% records. While this method cannot fully replace the utility of
+%% pattern matching, it does allow a fair bit of functionality on
+%% records without the need for compile-time dependencies.
+%%
+%% Whenever record definitions need to be exported from a module,
+%% inserting a compiler attribute,
+%%
+%% export_records([RecName, ...])
+%%
+%% causes this transform to lay out access functions for the exported
+%% records:
+%%
+%% -module(foo)
+%% -compile({parse_transform, diameter_exprecs}).
+%%
+%% -record(r, {a, b, c}).
+%% -export_records([a]).
+%%
+%% -export(['#info-'/1, '#info-'/2,
+%% '#new-'/1, '#new-'/2,
+%% '#get-'/2, '#set-'/2,
+%% '#new-a'/0, '#new-a'/1,
+%% '#get-a'/2, '#set-a'/2,
+%% '#info-a'/1]).

+%% '#info-'(RecName, fields).

+%% '#new-'(r, Vals) -> '#new-r'(Vals)

+%% '#get-r'(Attrs, Rec).
