Eli Friedman fe0739dffb Some small improvements to the builtin (-ffreestanding) stdint.h; in 
particular, make sure to handle WCHAR_MIN correctly.

Daniel Dunbar 540e8b1dcd Headers: Change [u]intmax_t to be defined in terms of __[U]INTMAX_TYPE__, instead of intN_t.

Daniel Dunbar cfc12ddb0a Headers: Hide intptr_t and uintptr_t definitions behind _INTPTR_T and _UINTPTR_T 
defines, for increased compatibility with Darwin gcc.
 - This is a bit of a hack, since platform compatibility issues don't belong
   here, but I don't think this hurts anyone either.

other limit macros.

Ken Dyck f0b343f5b7 Parameterize WINT_MIN and WINT_MAX with __WINT_WIDTH__ to support arbitrary 
widths. This corrects the values of these definitions for MSP430 and PIC16.

__INTMAX_WIDTH__.

 2009-11-18 18:57:04 +00:00
Ken Dyck 19ac306c2c Replace (-INT8_C(128)), which uses an illegally out-of-range argument for 
INT8_C, with (-INT8_C(127)-1) in the definition of INT8_MIN. Apply similar
changes to the definitions of INT16_MIN and INT24_MIN.

 2009-11-17 18:29:12 +00:00
Ken Dyck f78dc738a5 Use the INTn_C integer constant macros to generate limit constants with correct 
suffixes. This corrects the suffixes for the limit constants of the 32-bit
types on MSP430 and PIC16, and the 64-bit types on PPC64, SystemZ, X86_64.

llvm-svn: 89101
 2009-11-17 16:26:27 +00:00
Ken Dyck e115235705 Remove unnecessary parens around the bodies of integer constant macros. C99 
requires that their arguments be decimal, hex, octal constants---no signs
allowed---making the parens unnecessary.

llvm-svn: 89095
 2009-11-17 13:54:02 +00:00
Ken Dyck 2dc8d5fa3e Parameterize the constant-generating macros in stdint.h with new built-in 
__INTn_C_SUFFIX__ macros that are defined for types with corresponding
constant suffixes (i.e. long and long long).

Chris Lattner 55c9877b66 Generalize stdint.h for non-8-bit-multiple types, patch by 
Ken Dyck!

"This adds definitions for types of 8-bit multiples
from 8 to 64 to stdint.h and rationalizes the selection of types 
for the exact-width definitions in InitPreprocessor.cpp."

llvm-svn: 86977
 2009-11-12 08:08:27 +00:00
Chris Lattner b0966de585 A simple reordering of the definitions in stdint.h and 
introduces no new function changes.   Patch by Ken Dyck!

Eli Friedman 7df3447c10 Fix for PR3841: follow gcc's example and fall back to the system 
stdint.h unless we are freestanding.

Any suggestions here are welcome.

Chris Lattner 61639745b6 glibc plays some weird games with multiple different definitions of 
int8_t and games it with strange *_defined macros.  Emulate its weirdness
for better compatibility with linux etc.  Problem pointed out by anders 
johnson.

Chris Lattner 39bb0182bd anders johnson points out that some software depends on the 
definition of __intptr_t_defined when stdint.h defines intptr_t.

Chris Lattner 7e4c81c8c6 Give TargetInfo a new IntPtrType to hold the intptr_t type for 
a target.

Make Preprocessor.cpp define a new __INTPTR_TYPE__ macro based on this.

On linux/32, set intptr_t to int, instead of long.  This fixes PR3563.

Anders Carlsson 7325b61e74 Fix an #ifndef that should be an #ifdef instead.

Chris Lattner 4293c8935a C++ really shouldn't check these #defines, thanks to Howard 
for pointing this out!

Chris Lattner 6726d42059 remove two eroneous suffixes, these promote to int. Thanks to Neil

Chris Lattner a7cc1267cf fix some missing parens, thanks for Eli's review! 
Obviously I make a miserable header developer :)

llvm-svn: 64009
 2009-02-07 06:42:04 +00:00
Chris Lattner 5455db4273 make sure that UINTMAX_MAX has an unsigned type. This assumes that 
uintmax_t is unsigned long long, which is not optimal, but is assumed 
elsewhere already.

llvm-svn: 64007
 2009-02-07 06:38:06 +00:00
Chris Lattner 6bda45cec0 make various MAX/MIN constants be preprocessor constants, not C constants. 
Thanks to Eli for pointing this out.

Chris Lattner 01af63beb4 Apparently it is important to define intptr_t and uintptr_t to 
long instead of int.  This is because system heaers like to redefine
typedefs and that is an error if they don't exactly match.  Use long
for intptr_t on all systems where long is the right size.
