17 ## This file is read several times:
18 ## - once per *extension* (not per language) for generic compilation rules
19 ## - once for each file which requires specific flags.
21 ## Note it is on purpose we wrote "if %AMDEP%", since:
23 ## - if deps are turned off, %AMDEP% is mapped onto FALSE, and therefore
24 ## the "if FALSE" chunk is removed (automake-time conditionals).
26 ## - if deps are on, %AMDEP% is mapped onto AMDEP, and therefore
27 ## the "if AMDEP" chunk is prefix with @AMDEP_TRUE@ just like for any
28 ## other configure-time conditional.
30 ## We do likewise for %FASTDEP%; this expands to an ordinary configure-time
31 ## conditional. %FASTDEP% is used to speed up the common case of building
32 ## a package with gcc 3.x or later. In this case we can skip the use of
33 ## depcomp and easily inline the dependency tracking.
35 ## Verbosity of FASTDEP rules
36 ## --------------------------
37 ## (1) Some people want to see what happens during make. They think
38 ## @-commands are evil because hiding things hinders debugging.
39 ## (2) Other people want to see only the important commands--those that
40 ## may produce diagnostics, such as compiler invocations. They
41 ## do not care about build details such as dependency generation
42 ## (the if/then/else machinery in FASTDEP rules). Their point is
43 ## that it is hard to spot diagnostics in a verbose output.
44 ## (3) Other people want "make -s" to work as expected: silently.
45 ## This way they can spot any diagnostic really easily.
47 ## The second point suggests we hide rules with @ and that we 'echo'
48 ## only the relevant parts. However this goes against the two others.
49 ## There are regular complaints about this on the mailing list, but
50 ## it's hard to please everybody. On April 2003, William Fulton (from
51 ## clan (3)) and Karl Berry (from clan (2)) agreed that folding the
52 ## compile rules so that they are output on a single line (instead of 5)
53 ## would be a good compromise. Actually we use two lines rather than one,
54 ## because this way %SOURCE% is always located at the end of the first
55 ## line and is therefore easier to spot. (We need an extra line when
