[Bug c/50987] New: powerpc: size of unnamed array is negative when compiling wine
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50987
Bug #: 50987
Summary: powerpc: size of unnamed array is negative when
compiling wine
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: austinengl...@gmail.com
Found while compiling wine on PowerPC. This did not occur on an older powerpc I
used on the gcc compiler farm, but I'm not sure what gcc/glibc/etc. versions
they had.
Bug is present in, at least:
gcc-4.0.0
gcc-4.1.0
gcc-4.2.0
gcc-4.6.1
trunk 4.7.0 2003
reduced testcase:
[austin@gcc1-power7 tests]$ cat generated.i
typedef int BOOL, *PBOOL, *LPBOOL;
typedef int INT, *PINT, *LPINT;
typedef struct _CACHE_DESCRIPTOR { BYTE Level; BYTE Associativity;
WORD LineSize; DWORD Size; PROCESSOR_CACHE_TYPE Type; }
*HDC;
typedef BOOL ( *ABORTPROC)(HDC, INT);
static void test_pack_ABORTPROC(void) { extern void __C_ASSERT__(int
[(sizeof(ABORTPROC) == 4)?1:-1]); TEST_TYPE_ALIGN (ABORTPROC, 4) }
gcc generated.i
generated.i:3:18: error: unknown type name 'BYTE'
generated.i:3:18: error: unknown type name 'BYTE'
generated.i:3:18: error: unknown type name 'WORD'
generated.i:3:18: error: unknown type name 'DWORD'
generated.i:3:18: error: unknown type name 'PROCESSOR_CACHE_TYPE'
generated.i: In function 'test_pack_ABORTPROC':
generated.i:6:4: error: size of unnamed array is negative
generated.i:6:124: error: expected expression before 'ABORTPROC'
generated.i:6:138: error: expected ';' before '}' token
if you have wine available, try compiling dlls/gdi32/tests/generated.c
[austin@gcc1-power7 tests]$ uname -a

the same works on (at least) x86/x86_64.

Wine automatically sets -m32 on x86_64, but not other architectures. The other powerpc machine I used was apparently 32-bit. Sorry for the noise.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66697 --- Comment #1 from austinenglish at gmail dot com --- We're now up to at least 9 bugs reported in Wine's bugzilla about this issue, it does not appear to be an isolated problem. E.g., Unity and for some applications, like Planetside 2, there is no 32-bit version, so the game is completely broken on wine. Is there any plan to implement this in a future version?

[Bug c/49053] New: Please add an option to catch empty statements (-Wempty-statement ?)

It would be useful to have an option to catch empty statements, e.g.:
#include
int main(void)
{
;;
return 0;
}
a la -Wempty-body does currently.
I've seen this happen a few times recently in Wine, especially when expanding
macros, e.g,.:

The only way to get a working wine was to compile gcc with --enable-frame-pointer.
