1 # RUN: yaml2obj %s -o %t
3 ## The binary used in this test can be built (on OSX) as follows:
4 ## main.c:
5 ## __attribute__((used)) static int a[1021];
6 ## __attribute__((used)) static char b = 1;
7 ## int main() {
8 ## return 0;
9 ## }
10 ## build command:
11 ## clang -fno-exceptions -fno-unwind-tables main.c -o main.exe
12 ## Note, that the variable "b" (whose size is 1) is placed into __DATA,__data section,
13 ## the array "a" (whose size is 4 * 1021 = 4084) is placed into __DATA,__bss and
14 ## __DATA,__bss is 16-byte aligned. In this case the total vmsize narrowly crosses
15 ## the border of one page (4096) and the final value should be equal to 8192.
17 # RUN: llvm-objcopy %t %t.copy
18 # RUN: cmp %t %t.copy
20 ## This additionally verifies that the binary created by llvm-objcopy/yaml2obj is valid.
21 # RUN: llvm-readobj --sections %t.copy
