llvm-project/lld/test/elf/tls-tbss-size.test

# This test verify if external TLS non initialized variables (tbss) are
# accounted in TBSS segment size

# The input file 'test/elf/Inputs/tls-tbss-size.yaml' declares:
#
# __thread int t0;       
# __thread int t1;
# __thread int t2;
# __thread int t3;        
#
# And the 'test/elf/tls-tbss-size.test' defines: 
#
# __thread int t4;                                                                          
# __thread int t5;
# __thread int t6;             
# __thread int t7;
#
# __thread int t8 = 3;                 
# __thread int t9 = 4;    
# __thread int t10 = 5;
# __thread int t11 = 6;
