[v4,6/7] ld: Add tests for -z nosectionheader and --strip-section-headers
Checks
Commit Message
Add tests to verify that the linker option, -z nosectionheader and
objcopy and strip option, --strip-section-headers, work correctly as well
as linker issues an error when dynamic symbol table from PT_DYNAMIC
segment is used.

This test failed on PPC where readelf outputs
7: 0000000000000000 0 FUNC GLOBAL DEFAULT [<localentry>:
8] UND puts@GLIBC_2.17 (2)
instead of
7: 0000000000000000 0 FUNC GLOBAL DEFAULT UND puts@GLIBC_2.17 (2)
Alan, what is the best way to deal with it?
Thanks.

I would replace DEFAULT with DEFAULT.*, but this test has a quite a
few other problems.
We should be using run_host_cmd everywhere we invoke a compiler in the
ld testsuite, if we want to use ld/ld-new just built. run_host_cmd
properly inserts $gcc_B_opt in cases where a user wants to test
binutils with a newly built compiler, ie. when $CC specifies -B itself.
Also, it is not good practice to exclude tests when non-native except
of course those tests that run a target binary. Compiling and linking
often shows up problems, before you get complaints from people running
natively.
The following gives me clean results on the test, except for
mips-linux-gnu +FAIL: Build pr25617-1a-now-no-sec-hdr.so (none)
mips-linux-gnu +FAIL: Build pr25617-1a-now-no-sec-hdr.so (objcopy)
mips-linux-gnu +FAIL: Build pr25617-1a-now-no-sec-hdr.so (strip)
and those are due to the .so being built with --hash-style=gnu which
results in DT_MIPS_XHASH on mips. I'm unsure what the correct fix is
for mips, it might just be a simple readelf change.
* testsuite/ld-elf/no-section-header.exp (binutils_run_test):
Use run_host_cmd to invoke $CC_FOR_TARGET. Run all tests
non-native too, except for attempting to run the binaries.
Run tests for ELF in general, not just linux.
* testsuite/ld-elf/pr25617-1-no-sec-hdr.rd: Allow localentry
symbol decoration, and support either sorting of symbols.
* testsuite/ld-elf/pr25617-1a-no-sec-hdr.rd: Likewise.
* testsuite/ld-elf/pr25617-1a-sec-hdr.rd: Likewise.
* testsuite/ld-elf/pr25617-1a-no-sec-hdr.nd: Accept D function syms.
* testsuite/ld-elf/start-shared-noheader-sysv.rd: Accept
mips-sgi-irix symbol output.
* testsuite/ld-elf/start-shared-noheader.nd: Likewise.
