While here, delete #ifdef to handle ns32k -- I don't think that's
gonna be relevant any time soon; in case you hadn't noticed, the
world has moved on from ns32k to vax by now.
PR 57881
Not sure if this'll work for all ports -- we might need to split it
up finer-grained by different m68k flavours -- but let's give it a
try and see what breaks.
This will reduce the risk of accidentally adding or deleting the
wrong symbols while fixing the aliases.
(This is all the architectures I have a build tree for handy; can add
other architectures like m68k later.)
Ancient 4.3BSD used short and int for location, file size, file type,
and addresses etc. but all of them should be unsigned.
Also rename several variables and add comments for readability.
The LIF file system info can be found in "The HPDir Project" page:
https://www.hp9845.net/9845/projects/hpdir/
The same uboot.lif binaries are generated.
The tests in C11 and C23 mode look the same right now but will change
soon.
The warnings in the C11 test disappeared because after the first error,
warnings about unused variables are suppressed by check_variable_usage,
as they are often wrong.
Not all variables that start with '.' are internals,
and unless they are explicitly flagged as internal should go
into .MAKEOVERRIDES
Update varname-dot-makeoverrides to check this.
Also avoid using SCOPE_CMDLINE when ReadOnly will do.
STRONG_ALIAS copies the symbol size and type, so it avoids warnings
like this:
/home/riastradh/netbsd/10/obj.vax/tooldir/bin/../lib/gcc/vax--netbsdelf/10.5.0/../../../../vax--netbsdelf/bin/ld: warning: type and size of dynamic symbol `ldexpl' are not defined
1. Instead of calling out VAX by name, use #ifdef NAN.
2. Verify signbit works on long double on all architectures, not just
those with __HAVE_LONG_DOUBLE which means long double is _larger_
than double.
3. Minor formatting tidying.
- KNF and add some newlines per blocks
- define and use proper bintobcd() macro
- make local functions and variables static
The same uboot.lif binaries are generated.
Conversion from uint64_t to long double should work on all ports,
including those where long double is the same as double, i.e., where
__HAVE_LONG_DOUBLE is undefined.
Instead, conditionalize the test cases on how many bits of precision
long double has in the significand, according to LDBL_MANT_DIG. The
conditionals here should handle binary128, powerpc double-dekker
(~106-bit precision), x86 extended precision (80-bit), m68k extended
precision (80-bit), and VAX D (56-bit).
If long double is the same as double, i.e., __HAVE_LONG_DOUBLE is
undefined, these tests should still pass, since they don't rely on
extra precision beyond double.
long double and LDBL_EPSILON work even on architectures where long
double is the same as double, i.e., where the confusingly named
__HAVE_LONG_DOUBLE is not defined.
cosl should always be defined even on architectures where long double
is the same as double so the confusingly named __HAVE_LONG_DOUBLE is
not defined.
__HAVE_LONG_DOUBLE just means long double is different from double.
This test should always pass on all ports, even if long double is the
same as double; it doesn't test any additional precision.
