/* Check if array arguments of ObjC methods are decayed to pointer types in a proper fashion: (1) The _encodings_ for the array arguments should remain to be '[4i]' and such, since this has been the case since at least gcc 3.3. (2) However, when building the static C functions out of ObjC method signatures, we need to decay the arrays into pointers (as C does). (3) If array size is not known (e.g., 'int a[]'), then the type shall be encoded as a pointer. */ /* Contributed by Alexander Malmberg <alexander@malmberg.org> */ #include "../objc-obj-c++-shared/TestsuiteObject.m" #include "../objc-obj-c++-shared/runtime.h" #include <stdlib.h> #include <stdio.h> #define CHECK_IF(expr) if(!(expr)) abort() @interface Test : TestsuiteObject { float j; } -(void) test2: (int [5])a with: (int [])b; -(id) test3: (Test **)b; /* { dg-message "previous declaration of .\\-\\(id\\)test3:\\(Test \\*\\*\\)b." } */ @end @implementation Test -(void) test2: (int [5])a with: (int [])b { a[3] = *b; } -(void) test3: (Test [3][4])b { /* { dg-warning "conflicting types for .\\-\\(void\\)test3:\\(Test \\\[3\\\]\\\[4\\\]\\)b." } */ } @end int bb[6] = { 0, 1, 2, 3, 4, 5 }; int *b = bb; Test *cc[4]; Test **c = cc; int offs1, offs2, offs3, offs4, offs5, offs6; int main(int argc, char **argv) { Class testClass = objc_getClass("Test"); Method meth; cc[0] = [Test new]; CHECK_IF (bb[3] == 3); [*c test2: b with: bb + 4]; CHECK_IF (bb[3] == 4); bb[3] = 0; [*c test2: bb with: bb + 5]; CHECK_IF (bb[3] == 5); meth = class_getInstanceMethod(testClass, @selector(test2:with:)); offs1 = offs2 = offs3 = offs4 = offs5 = offs6 = -1; sscanf(method_getTypeEncoding(meth), "v%d@%d:%d[%di]%d^i%d", &offs1, &offs2, &offs3, &offs4, &offs5, &offs6); CHECK_IF (!offs2 && offs4 == 5 && offs3 > 0); CHECK_IF (offs5 == 2 * offs3 && offs6 == 3 * offs3 && offs1 == 4 * offs3); meth = class_getInstanceMethod(testClass, @selector(test3:)); offs1 = offs2 = offs3 = offs4 = offs5 = offs6 = -1; sscanf(method_getTypeEncoding(meth), "v%d@%d:%d[%d[%d{Test=#f}]]%d", &offs1, &offs2, &offs3, &offs4, &offs5, &offs6); CHECK_IF (!offs2 && offs4 == 3 && offs5 == 4 && offs3 > 0); CHECK_IF (offs6 == 2 * offs3 && offs1 == 3 * offs3); return 0; }
