originally, this was meant to avoid 'void' values leak
to the gen-xxx.c generators which would otherwise try
to load void from/to registers. Also catch invalid types
such as 'unsigned bool' eariler.
tccgen.c:
- expr_cond()/gexpr(): ignore VT_VOID
- gen_cast(): set float reg with static initializers to make
backends happier with invalid input
- init_putv():
improve static compound literal initializers
Also:
- ignore "missing prototype" and "might return no value"
for old style K&R functions
tcc.c, libtcc.c:
- tcc_set_output_type(): return errors from loading crt1.o
tcc.h/tccpp.c:
- fix horrible longstanding mistake with sizeof SValue.tab.
Must have place for sizeof (long double) rather than the
target's LDOUBLE_SIZE.
tccdefs.h:
- add a fake __[u]int128_t for all platforms
arm-gen.c:
- gen_cvt_ftof() must load to reg always
arm64-gen.c:
- simplify arm64_pcs() a bit
i386/x86_64-gen.c:
- do not assume char is signed (for cross compilation arm->x86)
tccelf/macho linker message:
- instead of
"undefined symbol 'X'"
now say
"unresolved reference to 'X'"
which makes it more clear that it is a _linker_error_.
tccasm.c:
- .align/p2align: use 'nop's in exec sections
