## This test ensures llvm-nm emits a helpful error message when dumping a symbol table ## whose sh_size isn't a multiple of the symbol size (sh_size % sizeof(Elf_Sym) != 0). ## a) Broken .symtab symbol table. Valid .dynsym symbol table. # RUN: yaml2obj -DBITS=32 -DSIZE=33 -DDYNSIZE=32 %s -o %t.32-bit.o # RUN: not llvm-nm %t.32-bit.o 2>&1 | FileCheck -DSIZE=33 -DSYMSIZE=16 -DINDEX=2 %s # RUN: yaml2obj -DBITS=64 -DSIZE=49 -DDYNSIZE=48 %s -o %t.64-bit.o # RUN: not llvm-nm %t.64-bit.o 2>&1 | FileCheck -DSIZE=49 -DSYMSIZE=24 -DINDEX=2 %s ## b) Broken .dynsym symbol table.
