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