This is https://bugs.llvm.org/show_bug.cgi?id=45698. Specification says that "Loadable segment entries in the program header table appear in ascending order, sorted on the p_vaddr member." Our `toMappedAddr()` relies on this condition. This patch adds a warning when the sorting order of loadable segments is wrong. In this case we force segments sorting and that allows `toMappedAddr()` to work as expected. Differential revision: https://reviews.llvm.org/D92641

## Check that we emit an appropriate warning when the dynamic string table ends past the end of the file.
|
|
|
|
## Case A: the value of DT_STRSZ tag is set so that the string table ends
|
|
## right before the EOF. No warning should be emitted.
|
|
# RUN: yaml2obj %s -DSTRSZ=0x210 --docnum=6 -o %t9.1
|
|
# RUN: llvm-readobj --dynamic-table %t9.1 | \

|
## Note: The code reads the data in [DT_STRTAB, DT_STRTAB + DT_STRSZ] as the string table
|
|
## as normal. Since the file ends with a zero byte, strings are dumped, but if it didn't,
|
|
## we'd get <?> printed instead. The important bit is that we don't get the past the end warning.
