pk 086b942780 Add `tu' and `tl' variable expansion modifiers, which transform the

reinoud a233fbd53e Fix major bug in make(1) ... due to shadowing of the dotLast path used for
the .DOTLAST primitive by a boolean variable with the same name, this whole
mechanism was broken ... it doesn't save much stat calls but it was wrong.

Thanks to Jason Thorpe for the other shadow-variable fixing patches he
made.

lukem a269984793 - partially fix ${foo:?true:false} so that at least it now parses ok and
the true result works. for some reason the false result doesn't, even
  though make -dv shows it being set as the result. (blah!)
- add braces in comments to fix vi showmatch

sjg e28cc22621 Add 4th arg (flags) to Var_Set so that VarLoopExpand can tell it not
to export interator variables when using context VAR_CMD.

sjg fc0df160d8 Simplify the exporting of VAR_CMD's via MAKEFLAGS.
We now just list the names of such variables in .MAKEOVERRIDES.
When we come to export MAKEFLAGS we quote the value of each exported variable
using :Q, using: ${.MAKEOVERRIDES:O:u:@v@$v=${$v:Q}@}
The :O:u suppresses duplicate names.
Also modifed Parse_DoVar to re-export MAKEFLAGS whenever .MAKEOVERRIDES
is assigned to so .MAKEOVERRIDES+= PATH will export PATH=${PATH:Q}
to the environment, while .MAKEOVERRIDES= will disable export of VAR_CMD's.

sjg d7c22ce2d7 Do a better job of duplicate suppression in .MAKEOVERRIDES.
From Var_Set: We actually want the equivalent of
.MAKEOVERRIDES:= ${.MAKEOVERRIDES:Nname=*} name='val'
clearing the previous value for name is important, since
doing simple duplicate suppression does not handle:
$ make FOO=goo
which then runs a sub-make with FOO=boo
the commands from that sub-make should see just FOO=boo.

sjg 44372a7be4 Modify handling of command line variable assignments and their exporting
via MAKEFLAGS.  Instead of appending them directly to .MAKEFLAGS, put
them in .MAKEOVERRIDES (and ensure they are quoted).  This is now done
in Var_Set when it exports VAR_CMD's.
Use ExportMAKEFLAGS() to export MAKEFLAGS, using the combined content
of .MAKEFLAGS and .MAKEOVERRIDES (with duplicate supression).
If .MAKEFLAGS is assigned to in a Makefile, ExportMAKEFLAGS is called again.
This allows a line like:
.MAKEOVERRIDES=
to effectively stop the exporting of the command line vars in MAKEFLAGS.

explorer 4b9b13c33f Perform variable expansion on sysv rhs patterns. That is, expand ${O} in: ${SRCS:.c=.${O}} 2001-06-05 06:00:39 +00:00
sjg 9cfd89292b A number of semi-related changes.
1. make -dx turns on DEBUG_SHELL which causes sh -x to be used where
   possible.
2. PrintOnError() is now called when make is stopping due to an error.
   This routine reports the curdir and the value of any variables listed
   in MAKE_PRINT_VAR_ON_ERROR.
3. Variables set via command line, are propagated to child-makes via
   MAKEFLAGS.  This behaviour appears to be necessary for POSIX (according
   to the GNU folk anyway).
4. Do not reset MAKEFILE when reading ".depend" as this rather eliminates the
   usefulness of ${MAKEFILE}.
5. Added ${.newline} as a simple means of being able to include \n in the
   result of a :@ loop expansion.
6. Set ${MAKE_VERSION} if defined.  Need to come up with a useful value.

sjg cd8908a299 Rats! ${FOO:=bar} is a common usage of the SysV = modifier.
To avoid that, we now do ::[+?!]*= but the SysV = modifier can
conflict with any new modifier.  At there are currently no Makefiles
in our tree that use ${FOO::=bar}

sjg 339f702f71 Implemented a set of assignment modifiers. These solve obscure
problems such as using modifiers on .for loop iterators derived from
local variables (eg .TARGET).
Unless the variable already exists in a global context, these assignments are
local to the current context (this is usually what is wanted).

sjg edfc5b4270 Expand variables in variable name passed to Var_Set and Var_Append.
This allows ${FOO}.bar=fubar etc to work.
This does not impact any Makefiles in the current tree but allows

sjg 5fe132c5cb Added the :U :D :L :P :! and :@ modifiers as used by ODE make.
These allow some very useful magic in the makefiles.
The comment in var.c describing their behaviour is mostly lifted
from ODE make, but the implementation of the modifiers themselves
is quite different (much simpler) due to divergence of our code base.

sommerfeld bcb141e5d0 Reuse the Hash_Entry `name' field to store the variable name when we
can (i.e., everything except environment variables, which aren't
stored in hash tables).

While we're here, inline the body of VarDelete into Var_Delete since
it's the only caller and it's just simpler that way when v->name can
share storage with the hash entry and may not need to be freed
separately.

Speeds up the infamous libc build benchhmark maybe 1% on PIII, 4% on
alpha pc164

Suggested by Perry Metzger.
