From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/obj-c++.dg/encode-5.mm | 95 ++++++++++++++++++++++++++++++++++++ 1 file changed, 95 insertions(+) create mode 100644 gcc/testsuite/obj-c++.dg/encode-5.mm (limited to 'gcc/testsuite/obj-c++.dg/encode-5.mm') diff --git a/gcc/testsuite/obj-c++.dg/encode-5.mm b/gcc/testsuite/obj-c++.dg/encode-5.mm new file mode 100644 index 000000000..18db3f3dd --- /dev/null +++ b/gcc/testsuite/obj-c++.dg/encode-5.mm @@ -0,0 +1,95 @@ +/* Method encoding tests for stand-alone @protocol declarations. */ +/* Contributed by Ziemowit Laski . */ +/* { dg-do run } */ +/* { dg-xfail-run-if "Needs OBJC2 ABI" { *-*-darwin* && { lp64 && { ! objc2 } } } { "-fnext-runtime" } { "" } } */ +#include "../objc-obj-c++-shared/Object1.h" +#include "../objc-obj-c++-shared/next-mapping.h" +#include "../objc-obj-c++-shared/Protocol1.h" +#ifdef __cplusplus +#define ProtoBool bool +#else +#define ProtoBool _Bool +#endif + +#ifdef __NEXT_RUNTIME__ +#define METHOD Method +#else +#include +#define METHOD Method_t +#define method_get_types(M) (M)->method_types +#endif + +#include +#include + +#define CHECK_IF(expr) if(!(expr)) abort() + +enum Enum { + zero, one, two, three +}; +typedef enum Enum Enum; +typedef signed char ObjCBool; /* as used by the NeXT runtime */ + +@protocol Proto +union __XXAngle { unsigned int alpha, beta; }; +typedef struct { float x, y; union __XXAngle a; } XXPoint; +typedef struct { double width, height; } XXSize; +typedef struct _XXRect { XXPoint origin; XXSize size; struct _XXRect *next; } XXRect; +- (void) char:(signed char)c float:(float)f double:(double)d unsigned:(unsigned)u short:(short)s long:(long)l; +- (void *)setRect:(XXRect)r withBool:(ProtoBool)b withInt:(int)i; ++ (Enum *)getEnum:(XXPoint *)pt enum:(enum Enum)e bool:(ObjCBool)b; ++ (ProtoBool **)getBool:(ObjCBool **)b; +@end + +Protocol *proto = @protocol(Proto); +struct objc_method_description *meth; + +unsigned totsize, offs0, offs1, offs2, offs3, offs4, offs5, offs6, offs7; + +static void scan_initial(const char *pattern) { + totsize = offs0 = offs1 = offs2 = offs3 = offs4 = offs5 = offs6 = offs7 = (unsigned)-1; + sscanf(meth->types, pattern, &totsize, &offs0, &offs1, &offs2, &offs3, + &offs4, &offs5, &offs6, &offs7); + CHECK_IF(!offs0 && offs1 == sizeof(id) && offs2 == offs1 + sizeof(SEL) && totsize >= offs2); +} + +int main(void) { + const char *string; + + meth = [proto descriptionForInstanceMethod: @selector(char:float:double:unsigned:short:long:)]; + if (sizeof (long) == 8) + string = "v%u@%u:%uc%uf%ud%uI%us%uq%u"; + else + string = "v%u@%u:%uc%uf%ud%uI%us%ul%u"; + scan_initial(string); + CHECK_IF(offs3 == offs2 + sizeof(int) && offs4 == offs3 + sizeof(float)); + CHECK_IF(offs5 == offs4 + sizeof(double) && offs6 == offs5 + sizeof(unsigned)); + CHECK_IF(offs7 == offs6 + sizeof(int) && totsize == offs7 + sizeof(long)); + meth = [proto descriptionForInstanceMethod: @selector(setRect:withBool:withInt:)]; + scan_initial("^v%u@%u:%u{_XXRect={?=ff(__XXAngle=II)}{?=dd}^{_XXRect}}%uB%ui%u"); + CHECK_IF(offs3 == offs2 + sizeof(XXRect) && offs4 == offs3 + sizeof(int)); + CHECK_IF(totsize == offs4 + sizeof(int)); + meth = [proto descriptionForClassMethod: @selector(getEnum:enum:bool:)]; + /* Here we have the complication that 'enum Enum' could be encoded + as 'i' on __NEXT_RUNTIME_, and (most likely) as 'I' on the GNU + runtime.
