1dc92f8ff8 Fix indentation and run_test type
tcc_state.run_test is used as counter, not flag, so int is appropriate.
Also fix indentation garbled by last patch.

8a93ce106a elf: rewrite version support
so it isn't quadratic in number of symbols.  It's still quadratic
in number of lib/version combinations (at library load time the
sym versions are internalized), but that's much less a problem as
in practice only glibc uses sym versioning.

c505074a9f riscv: rewrite parameter passing
this fixes the ret_mixed_test of abitest.c, now everything of the
testsuite works.

The generic code for returns is good enough for our use, except in
the specific case of a mixed int/float structures returned in registers,
so instead of duplicating the whole generic gfunc_return function, add
another modus for gfunc_sret: returning -1 makes the actual register
transfer by a new backend function.

9b0efa9346 riscv: Make PLT reloc be AUTO_GOT
relocs against defined symbols are replaced by relative
relocs, when a GOT slot is created.  But code relocs (usually
calls via PLT) use the plt_offset member of attr, not the got_offset
member, so the "huh" warning was triggered in the case of calls to
static functions (the code still worked).

So, for now just use the AUTO_GOT_PLT mechanism.  We could also
emit a non-PLT reloc in the backend for calls to VT_STATIC functions
(like the x86-64 backend does) and do the same as for x86-64 in
build_got_entries (which transforms PLT32 into PC32 relocs, riscv
would transform CALL_PLT into CALL relocs).  Maybe later.

0cb6e3fff8 riscv: Fix mixed2 and mixed3 abi tests
this was caused by a simple bug, not by the current inability
to pass a {float,int} struct per psABI.  So now only ret_mixed_test
is still broken.

98f1b83ffe riscv: Start fixing float struct passing/returnig
this fixes ret_2float_test, ret_2double_test and
ret_8plus2double_test of abitest.c.  The common gfunc_return
actually works for these cases, so let's use that for now.

The ret_mixed_test (as well as mixed2 and mixed3) are left
broken, and tccgen.c:gfunc_return can't be used for that as is,
so I'll leave the gfunc_return implementation in riscv64-gen.c for
now, I'll have to think about this some more.

e9c2a1996a riscv: Fix tcctest.c

TCC with itself.  abitest.c doesn't yet work due to known

linking.

509f561823 riscv: fix more sign/zero-extension problems

the wrong thing, and it should break other archs.  Rework once
there are testcases for this.

1ada32900b riscv: Fix ftoi and ftof(long double->float)
float to int must be truncations, not normal rounding.
And ftof was typoed to select the wrong conversion function.

06184aec53 riscv: fix relocs for global syms
loads and stores to global symbols need to go via the
GOT (at least for weaks), otherwise -run doesn't work.
Ideally we'd generate GOT relocs (and loads) always and replace
them with PCREL relocs and adds during linking.

69c77d1597 riscv: Fix unsigned 32bit loads
the invariant for the risc-v codegen is, that 64bit regs
generally contain the sign-extension of a 32bit value.
This wasn't heeded by loads of 32bit values from memory, which
used lwu and ultimately caused a miscompilation in string_test
of tcctest.c.

Now most of tcctest.c works (not with -run, but with linking
a real executable), except some ftoi/ftof conversions.

2668eda595 riscv: Implement long double support
for the implementation of operations we can reuse the ones
from lib/lib-arm64.c, risc-v long double is also float128.
Also implement ggoto, and PDIV, and use t0 in load/store as
temporary register if necessary, not one given by get_reg
(the latter can destroy assignments of long double parameters
in function calls that are already set up).

This let's us compile tcc.c and tcctest.c, though both
don't yet work.

2616c6b230 riscv: Fix 73_arm.c
some constants were loaded wrong (e.g. 0xffffabcdU), and
risc-v needs to do explicit zero-extensions for widening from
32bit (not sign-extensions like the other 64bit targets).

This makes the whole tests2.all testsuite work.

Parameter passing is still not psABI-compliant, but internally
consistent.  (e.g. structs of two floats/doubles are passed
in integer registers, but should sit in float regs).

982de78e8d riscv: implement stdarg functions
this also fixes passing of params > 16 bytes.  In riscv
they aren't passed by value on stack, but via reference (and
because callees are allowed to modify by-ref params the caller must
allocate an own copy per call).

This fixes the stdarg parts of 73_arm.c.

f44df9d85b riscv: some work on large function arguments
like long double (16 bytes) and structs.  Not completely
correct, but 73_arm64 somewhat works now (when the stdarg part
is disabled), though with some errors.  What's definitely incorrect
is arguments of a mixed int/float struct.  I'm using VT_LDOUBLE
(which conveniently has to be placed in a int-reg-pair) to load/store
structure arguments of size > 8 and <= 16, and that can lead to
overreads.
