* ansify.c (main): Make sure readers of stdout know
|

it's derived from stdin; omit comment text; get source
|

line numbers in future stderr output to be correct.

|
||||
|
||||
Changes to allow g77 docs to be built entirely from scratch
|
||||
using any ANSI C compiler, not requiring GNU C:
|
||||
* Make-lang.in ($(srcdir)/f/intdoc.texi): "Pipe" new
|
||||
location of intrinsic documentation data base, f/intdoc.in,
|
||||
through new `ansify' program to append `\n\' to quoted
|
||||
newlines, into f/intdoc.h0. Do appropriate cleanups. Explain.
|
||||
(f77.mostlyclean): Add f/ansify and f/intdoc.h0 to cleanups.
|
||||
* f/ansify.c: New program.
|
||||
* f/intdoc.c: Fix so it conforms to ANSI C.
|
||||
#include f/intdoc.h0 instead of f/intdoc.h.
|
||||
Avoid some warnings.
|
||||
* f/intdoc.h, f/intdoc.in: Rename the former to the latter; no
|
||||
changes made to the content in this patch!
|
||||
* f/intrin.h (ffeintrinFamily): Fix to conform to ANSI C.

Sun Aug 24 06:52:48 1997 Craig Burley <burley@gnu.ai.mit.edu>
|
||||
|
||||
Fix up g77 compiler data base for libf2c routines:
|
||||
* com-rt.def (FFECOM_gfrtSIGNAL): Change return type to
|
||||
FTNINT to match actual code.
|
||||
|
||||
* com.c (ffecomRttype_): Replace FFECOM_rttypeINT_ with
|
||||
FFECOM_rttypeFTNINT_.
|
||||
Add and fix up comments.
|
||||
(ffecom_make_gfrt_, ffecom_gfrt_basictype,
|
||||
ffecom_gfrt_kindtype): Replace FFECOM_rttypeINT_ with
|
||||
FFECOM_rttypeFTNINT_; add FFECOM_rttypeDOUBLEREAL_.

|

* global.c (ffeglobal_ref_progunit_): It's okay to have
|
||||
a different CHARACTER*n length for a reference if the
|
||||
existing length is for another reference, not a definition.

||||

Mon Aug 18 14:27:18 1997 Craig Burley <burley@gnu.ai.mit.edu>
|

|

Fix 970814-0.f:
|
||||
* global.c (ffeglobal_new_progunit_): Distinguish
|
||||
between previously defined, versus inferred, filewide
|
||||
when it comes to diagnostics.
|
||||
|
||||
Fix 970816-1.f:
|
||||
* global.c (ffeglobal_ref_progunit_): Change BDATA into EXT
|
||||
right at the beginning, so EXTERNAL FOO followed later
|
||||
by SUBROUTINE FOO is not diagnosed.
|
||||
|
||||
Fix 970813-0.f:
|
||||
* com-rt.def (FFECOM_gfrtALARM): Returns `integer', not
|
||||
`void'.

Sun Aug 17 03:32:44 1997 Craig Burley <burley@gnu.ai.mit.edu>
|
||||
|
||||
Fix up problems when virtual memory exhausted:
|
||||
* malloc.c (malloc_new_): Use gcc's xmalloc(), so we
|
||||
print a nicer message when malloc returns no memory.
|
||||
(malloc_resize_): Ditto for xrealloc().
|
||||
|
||||
* Make-lang.in, Makefile.in: Comment out lines containing
|
||||
just formfeeds.

_real_type_node.

# directly, if f/intdoc.c #include'd that, but we don't want to force

# people to install gcc just to build the documentation. We use the

# C format for f/intdoc.in in the first place to allow a fairly "free",

# how to write texinfo source and enclose it in C constants can handle

# document snippets into a data base via name lookup, rather than duplicating

# that kind of code here. And we use f/intdoc.c instead of straight
|

# texinfo in the first place so that as much information as possible

# contained in f/intrin.def can be inserted directly and reliably into

# the documentation. That's better than replicating it, because it

# reduces the likelihood of discrepancies between the docs and the compiler

|

An old version of the BLAS function @code{DNRM2} is miscompiled
|
||||
on ix86 machines when @samp{-O2} (or higher, probably) is
|
||||
used.
|
||||
The bug is in the @code{gcc} back end, as proven using
|
||||
a C translation of a simplified version of @code{DRNM2}
|
||||
that illustrates the bug.
|
||||
(The code in @file{gcc/reg-stack.c} fails to recognize that,
|
||||
after an initial load of @samp{XMAX}, a subsequent load
|
||||
must be preceded by a stack pop, or @samp{fstp %st(0)} in
|
||||
assembler, to avoid ultimately overflowing the floating-point
|

stack.)

@code{g77}'s version of @code{gcc}, and probably @code{g77}
|
||||
itself, cannot be reliably used with the @samp{-O2} option
|
||||
(or higher) on Digital Semiconductor Alpha AXP machines.
|
||||
The problem is most immediately noticed in differences
|
||||
discovered by @kbd{make compare} following a bootstrap
|
||||
build using @samp{-O2}.
|
||||
It also manifests itself as a failure to compile
|
||||
@samp{DATA} statements such as @samp{DATA R/7./} correctly;
|
||||
in this case, @samp{R} might be initialized to @samp{4.0}.
|
||||
|
||||
Until this bug is fixed, use only @samp{-O1} or no optimization.

For example, the backslash at the end of the line is removed,

Use the (x86-specific) @samp{-malign-double} option when compiling

programs.
|
||||
This will align only static data (entities in @code{COMMON} or
|
||||
local entities with the @code{SAVE} attribute),
|
||||
but it should probably always be
|
||||
used with Fortran code on the 586 and 686 architectures for best
|
||||
performance.
|
||||
|
||||
This feature of @samp{-malign-double} means it may actually be best to
|
||||
use it with @samp{-fno-automatic} even though the latter usually
|
||||
produces worse code; at least, doing so will tend to produce more
|
||||
consistent run times.
|
||||
|
||||
Using @samp{-malign-double} and @samp{-fno-automatic} together is
|
||||
apparently the only way to ensure that all doubles are correctly aligned
|
||||
on GNU x86 systems without having to change @code{g77} itself as
|
||||
described in the next item.
|
||||
(Note that the @code{gcc} C extension @samp{__attribute__ ((aligned (8))}

also won't double-align the datum to which it is applied if that is allocated

on the stack.)

Ensure that @file{crt0.o} or @file{crt1.o}

aligned stack for @code{main()}.
|
||||
Some experimentation might be needed to determine this, and
|
||||
access to source code to fix this.
|
||||
While arranging this may typically
|
||||
get more data properly aligned, it won't, by itself,
|
||||
ensure they all are.
|
||||
|
||||
One approach to testing this is to write a @code{main()} program
|
||||
in C or assembler that outputs the address of the stack pointer
|
||||
(and/or frame pointer), and visually inspect the output to see
|
||||
if the stack is 64-bit aligned.
|
||||
If it is, try renaming the executable to longer and shorter names
|
||||
and running the program again.
|
||||
If the name of the executable is placed on the stack by @file{crt0.o}
|
||||
or @file{crt1.o},
|
||||
the location of the stack should move, and this might help determine
|
||||
whether it is kept on a 64-bit boundary.
|
||||
The recent one from GNU (@code{glibc2}) will do this on x86 systems,
|
||||
but we don't know of any other x86 setups where it will be right.

Read your system's documentation to determine if

it is appropriate to upgrade to a more recent version

to obtain the optimal alignment.

|
||||
The sizes shown below assume all languages distributed
|
||||
in @code{gcc-2.7.2.2}, plus @code{g77}, will be built
|
||||
and installed.
|
||||
These sizes are indicative of GNU/Linux systems on
|
||||
Intel x86 running COFF and on Digital Alpha (AXP) systems
|
||||
running ELF.
|
||||
These should be fairly representative of 32-bit and 64-bit
|
||||
systems, respectively.
|
||||
|
||||
It is likely that many systems don't require the complete
|
||||
bootstrap build, as they already have a recent version of
|
||||
@code{gcc} installed.
|
||||
Such systems might be able to build @code{g77} with only
|
||||
about 75MB of free space.
|
||||
Note that all sizes are approximate and subject to change without
|
||||
notice!
|
||||
They are based on preliminary releases of g77 made shortly
|
||||
before the public beta release.
|
||||
|
||||
@itemize ---
|
||||
@item
|
||||
@code{gcc} and @code{g77} distributions occupy 8.6MB
|
||||
packed, 35MB unpacked.
|
||||
These consist of the source code and documentation,
|
||||
plus some derived files (mostly documentation), for
|
||||
@code{gcc} and @code{g77}.
|
||||
Any deviations from these numbers for different
|
||||
kinds of systems are likely to be very minor.
|
||||
|
||||
@item
|
||||
A ``bootstrap'' build requires an additional 67.3MB
|
||||
for a total of 102MB on an ix86, and an additional
|
||||
98MB for a total of 165MB on an Alpha.
|
||||
|
||||
@item
|
||||
Removing @file{gcc/stage1} after the build recovers
|
||||
10.7MB for a total of 91MB on an ix86, and recovers
|
||||
??MB for a total of ??MB on an Alpha.
|
||||
|
||||
After doing this, the integrity of the build can
|
||||
still be verified via @samp{make compare}, and the
|
||||
@code{gcc} compiler modified and used to build itself for
|
||||
testing fairly quickly, using the copy of the compiler
|
||||
kept in @code{gcc/stage2}.
|
||||
|
||||
@item
|
||||
Removing @file{gcc/stage2} after the build further
|
||||
recovers 27.3MB for a total of 64.3MB, and recovers
|
||||
??MB for a total of ??MB on an Alpha.
|
||||
|
||||
After doing this, the compiler can still be installed,
|
||||
especially if GNU @code{make} is used to avoid
|
||||
gratuitous rebuilds (or, the installation can be done
|
||||
by hand).
|
||||
|
||||
@item
|
||||
Installing @code{gcc} and @code{g77} copies
|
||||
14.9MB onto the @samp{--prefix} disk for a total of 79.2MB
|
||||
on an ix86, and copies ??MB onto the @samp{--prefix}
|
||||
disk for a total of ??MB on an Alpha.
|
||||
@end itemize
|
||||
|
||||
After installation, if no further modifications and
|
||||
builds of @code{gcc} or @code{g77} are planned, the
|
||||
source and build directory may be removed, leaving
|
||||
the total impact on a system's disk storage as
|
||||
that of the amount copied during installation.
|
||||
|
||||
Systems with the appropriate version of @code{gcc}
|
||||
installed don't require the complete
|
||||
bootstrap build.
|
||||
Doing a ``straight build'' requires about as much
|
||||
space as does a bootstrap build followed by removing
|
||||
both the @file{gcc/stage1} and @file{gcc/stage2}
|
||||
directories.
|
||||
|
||||
Installing @code{gcc} and @code{g77} over existing
|
||||
versions might require less @emph{new} disk space,
|
||||
but note that, unlike many products, @code{gcc}
|
||||
installs itself in a way that avoids overwriting other
|
||||
installed versions of itself, so that other versions may
|
||||
easily be invoked (via @samp{gcc -V @var{version}}).
|
||||
|
||||
So, the amount of space saved as a result of having
|
||||
an existing version of @code{gcc} and @code{g77}
|
||||
already installed is not much---typically only the
|
||||
command drivers (@code{gcc}, @code{g77}, @code{g++},
|
||||
and so on, which are small) and the documentation
|
||||
is overwritten by the new installation.
|
||||
The rest of the new installation is done without
|
||||
replacing existing installed versions (assuming
|
||||
they have different version numbers).
