1 ## This test is based on a trimmed down version of the binary built as follows:
2 ## a.c:
3 ## __attribute__((used)) static int PrivateSymbol;
4 ## __attribute__((visibility("hidden"))) int PrivateExternalSymbol;
5 ## __attribute__((used)) int CommonSymbol;
6 ## extern int UndefinedExternalSymbol;
7 ## // Defined external symbol
8 ## int main() {
9 ## return PrivateSymbol + PrivateExternalSymbol + CommonSymbol +
10 ## UndefinedExternalSymbol;
11 ## }
12 ## build command:
13 ## clang -g -fno-exceptions -fno-unwind-tables -undefined dynamic_lookup \
14 ## a.c -o a.exe
15 ## All the load commands except the symbol table and its transitive dependencies
16 ## have been removed.
18 # RUN: yaml2obj %s -o %t
19 # RUN: llvm-objcopy %t %t.copy
20 # RUN: cmp %t %t.copy
22 ## Verify that the binary is valid and check its symbol table.
