the case in ISO mode, warning and run-time error in Extended Pascal mode
o warning enabled by default in all other modes for boolean, enumeration and
subrange integer types with ranges different from the default ones
(i.e., different from 0..255, -128..127, 0..65536, etc)

for the system unit, as there are several bugs in the Xcode linkers
that trigger when the system unit is involved:
o Xcode 9.3: the second symbol associated with routines that have multiple
symbols (such as FPC_INTERLOCKED*) gets moved to the next routine (so
e.g. calling InterlockedIncrement results in calling InterlockedExchange)
o Xcode 10.1: the linker does not generate native code for the personality
routine (probably because it's not referenced directly anywhere)

program/library also with -Clflto, all units compiled with that option
will be linked using their bitcode files and LTO
o compiling with -CLflto will compile all units twice: once for normal
(static or smart) linking, and once for LTO. So the result can be
used both with and without LTO.

information in OMF LINNUM records, in addition to the DWARF debug information.
This enables source level debugging on i8086-msdos, when using the Open Watcom
Debugger, provided the source was compiled with this option and the external
linker (wlink) was used for generating the executable (the internal linker
does not yet support generating debug information).
git-svn-id: trunk@39014 -

hopefully, soon it'll start emitting line number information for i8086-msdos
that is usable by DOS debuggers.

Note 1: using an older AS might fail anyway if the amount of sections is too high (like in packages\odata\src\sharepoint.pp)
Note 2: it might be an idea to keep track of the created sections in the asmlists and only enable the option if *really* necessary (like with the internal COFF output generator), though this might lead to false positives due to multiple sections with the same name (since I'd prefer to use the KISS principle only a counter would be used)

Add description to -gc option, saying it is experimental.

CPU target for inline assembler blocks. In addition to the different CPUs
(as listed under 'Supported CPU instruction sets:' in the output of 'fpc -i'),
it also supports the special values 'ANY' and 'CURRENT'. 'ANY' means no
restrictions (i.e. all instructions are available). 'CURRENT' means the
current CPU target (as specified with the '-Cp' command line option). For
backward compatibility, the default value is 'ANY' for all CPU targets, except
i8086, where it defaults to 'CURRENT'.
This directive requires support for the new asd_cpu directive in the assembler
writer. This is currently implemented only for NASM, but will be supported in
some of the other assembler writers as well (incl. the x86 internal assembler
writer).
git-svn-id: trunk@33138 -
the i8086 internal object writer. This allows weeding out spurious 386
instructions, as is similarly done by NASM when using it as an external
assembler.

how the fpc sections have to be linked *on Linux*. This prevents the
"did you forget -T" warnings from ld, and in general is more correct than
our previous approach of specifying a complete linker script without -T
and hoping that there won't be any unexpected interactions with ld's
built-in linker script (fixed version of r31664, thanks to Alan Modra)

are compatible with binutils older than 2.19 (reverts to the old

an Objective-C method masks an identifier from a category, because due

Please note that this warning won't be triggered if an instance of that class is created using a class variable of that class type as the compiler can not know the type contained in the variable at compile time (see also the added test).

Currently it is implemented only for x86-CPUs supporting the FMA extension. While it would
be possible to implement it in software or simulate fma(<single>,<single>,<single>) using
double operations, it makes no sense in my opinion to do so.
