llvm/test/tools/llvm-nm/invalid-symbol-table-size.test

## 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. Valid .symtab symbol table.
# RUN: yaml2obj -DBITS=32 -DSIZE=32 -DDYNSIZE=33 %s -o %t.32-bit.o
# RUN: not llvm-nm --dynamic %t.32-bit.o 2>&1 | FileCheck -DSIZE=33 -DSYMSIZE=16 -DINDEX=3 %s
# RUN: yaml2obj -DBITS=64 -DSIZE=48 -DDYNSIZE=49 %s -o %t.64-bit.o
# RUN: not llvm-nm --dynamic %t.64-bit.o 2>&1 | FileCheck -DSIZE=49 -DSYMSIZE=24 -DINDEX=3 %s

# CHECK: error: {{.*}} section [index [[INDEX]]] has an invalid sh_size ([[SIZE]]) which is not a multiple of its sh_entsize ([[SYMSIZE]])
