	lib: Define va_args for tinycc mob.
	In TinyCC (mob) there's a program that generates all the variable
	argument control code.  We don't use it in our bootstrapping system so
	we need to provide the headers for that ourselves.  We had the support
	done for 927, so just removing the version limit makes the support
	available for TinyCC (mob) too.

	* include/stdarg.h[__TINYC__]: Remove < 928 version selection.

	RISC-V: lib: Fixes for setjmp/longjmp.
	The a0 register had been clobbered by val and subsequent loads were
	failing.  Implementing it inside C function causes various other issues,
	such as compiler adding wrong return address after we loaded one from

	* lib/riscv64-mes-gcc/setjmp.c (longjmp): Remove function; Implement
	with single toplevel ASM statement catering for MesCC, TinyCC, and GCC.

2024-06-04  Janneke Nieuwenhuizen  <janneke@gnu.org>

	mes: Remove unused nyacc/lalr.mes.
	* mes/module/nyacc/lalr.mes: This is not currently used, and includes
	the non-bootstrappable psyntax.mes, which creates confusion.

2024-04-16  Ekaitz Zarraga  <ekaitz@elenq.tech>

	RISC-V: lib: Fixes for setjmp/longjmp.
	HAVE_FLOAT_ASM defines if there's assembly support for float
	instructions.

	HAVE_FLOAT defines if there's floating point arithmetic support.

	This is important for TinyCC because the assembler and the C compiler
	are split. TinyCC can HAVE_FLOAT but no assembler support for them.

	* lib/riscv64-mes-gcc/setjmp.c: Use HAVE_FLOAT_ASM/HAVE_FLOAT instead of
	__riscv_float_abi_soft.
	* lib/riscv64-mes-tcc/setjmp.c: Remove

2024-04-16  Ekaitz Zarraga  <ekaitz@elenq.tech>

	RISC-V: lib: make long jumps to __init_io and main
	`jalr` only supports 20 bit offsets that happened not to be enough when
	building large programs.  The jumps fell too short and that caused a
	segfault.  Making a C call instead, lets the compiler use an `auipc` +
	`jalr` combination, enabling longer jumps.

	* lib/linux/riscv64-mes-gcc/crt1.c (__init_io, main): Move out of
	extended asm to take advantage of call relocations.

2024-03-05  Ekaitz Zarraga  <ekaitz@elenq.tech>

	lib: Fix struct stat's fields for riscv64.
	We detected this behavior when building `make` with `tcc` during the
	bootstrapping process.  That resulting `make` rebuilt the files, even if
	they were just built.

	This problem broke the whole Guix bootstrapping process as the `check`
	phase was rebuilt in the `build` step because the `make` program was
	rebuilding everything by mistake.  This wouldn't be that much of a
	problem if it wasn't that the phase that patches the shebangs on the
	generated files is run after `check` and not after the "re-check" that
	was triggered during the `build` phase.  That made every generated file
	that was using `/usr/bin/sh` to explode.

	Other architectures (x86_64 is the most suspicious one) may have the
	same issue.

	NOTE: We used `musl` as a reference, but we have different field names,
	which ones should we keep?

	    Ours:                              Musl:
	      time_t         st_atime;           long st_atime_sec;
	      unsigned long  st_atime_usec;      long st_atime_nsec;
	      time_t         st_mtime;           long st_mtime_sec;
	      unsigned long  st_mtime_usec;      long st_mtime_nsec;
	      time_t         st_ctime;           long st_ctime_sec;
	      unsigned long  st_ctime_usec;      long st_ctime_nsec;

	* include/linux/riscv64/kernel-stat.h (struct stat): Introduce padding
	and fix field lengths.

2024-04-13  Michael Forney  <mforney@mforney.org>

	mescc: Fix length calculation of initialized array with unspecified length.
	Consider the following definition:

	    char a[] = {1, 2, 3};

	The initializer is parsed as

	    ((initzer (initzer-list
	        (initzer (p-expr (fixed "1")))
	        (initzer (p-expr (fixed "2")))
	        (initzer (p-expr (fixed "3"))))))

	so (cadar init) is

	    (initzer-list
	        (initzer (p-expr (fixed "1")))
	        (initzer (p-expr (fixed "2")))
	        (initzer (p-expr (fixed "3"))))

	We want to determine the number of items in the initializer, which
	is (length (cdadar init)), not (length (cadar init)).

	Using cadar causes the length of the array to be one too large and
	incorrect evaluation of sizeof.

	* module/mescc/compile.scm (init-declr->info): Fix length calculation
	of initialized array with unspecified length.

2024-04-13  Michael Forney  <mforney@mforney.org>

	mescc: Implement ast->type for comma-expr.
	This fixes code like

	    x = (1, 0);

	* module/mescc/compile.scm (ast->type): Implement ast->type for
	comma-expr.
	* build-aux/check-mescc.sh (xfail_tests): Remove
	86-comma-operator-types.

2024-04-13  Michael Forney  <mforney@mforney.org>

	lib: Fix buffer underflow with large integer in ntoab.
	With base == 8, -2^63 is converted as -1000000000000000000000, which
	is 24 bytes long (including terminating nul), so we need at least
	this much space in the __itoa_buf.

	* lib/mes/ntoab.c (ntoab): Allocate enough space for longest string, and
	update assert with lowest possible base.  Don't decrement pointer below
	start of buffer, even temporarily.

2024-04-14  Janneke Nieuwenhuizen  <janneke@gnu.org>

	build: Whitespace nitpicks.
	* build-aux/build-scaffold.sh: Use C-c C-\ to outline continuation backslashes.

2024-04-02  Michael Forney  <mforney@mforney.org>

	build: Pass LDFLAGS when linking test programs in scaffold step.
	The system gcc may default to building PIE executables (if configured
	with --enable-default-pie). This results in broken test binaries:

	  /bin/gcc -nostdlib -g lib/linux/x86_64-mes-gcc/hello-mes.S -o hello-mes
	  /bin/ld: /tmp/ccDIHhGp.o: warning: relocation in read-only section `.text'
	  /bin/ld: warning: creating DT_TEXTREL in a PIE
	  build-aux/build-scaffold.sh: line 92: 11246 Segmentation fault      ./hello-mes
	    => 139

	* build-aux/build-scaffold.sh: Pass LDFLAGS when linking.

	* include/stdint.h (CHAR_MIN): Assign according to char signedness.
	(CHAR_MAX): Likewise.

2024-02-27  Ekaitz Zarraga  <ekaitz@elenq.tech>

	tests: Add 86-comma-operator-types.c.
	The comma operator works when comparing values but not when it needs to
	deduce the type of the result.  This test checks that.

	* lib/tests/scaffold/86-comma-operator-types.c: New file.
	* build-aux/check-mescc.sh (tcc_tests): Add it.
	(xfail_tests): Likewise.

2024-02-24  Ekaitz Zarraga  <ekaitz@elenq.tech>

	lib: Add ucontext_t for all architectures.
	ucontext_t is used by `tcc -run` and it affects the compilation process
	of that.  If we don't have the data structures defined the build process
	of tcc-mob later in the chain fails.  We don't use the `-run` option for
	anything in the bootstrapping process, but as we do `ONE_SOURCE` that
	affect our building process.  The cleanest solution is to add the proper
	support here and forget about it.

	This commit copies the code from musl libc, using the GNU_SOURCE part of
	the `#ifdef`s in there as that's what tcc expects.  We can do better but
	the goal of the commit is to make the bare minimum.

	* include/signal.h (ucontext_t): Move current i386 support to...
	* include/gnu/x86/signal.h: ...this new file.
	* include/linux/x86/signal.h,
	include/linux/x86_64/signal.h,
	include/linux/arm/signal.h,
	include/linux/riscv64/signal.h: New files.
	* simple.sh: Add support for multiple signal.h files.
	* configure.sh: Likewise.
	* configure: Likewise.

	* module/mescc/compile.scm (convert-r0): use long-r instead of
	long-signed-r.
	* build-aux/check-mescc.sh (xfail_tests)[x86_64 && MesCC]: Add 16-cast,
	17-compare-unsigned-le.

2024-01-20  Andrius Štikonas  <andrius@stikonas.eu>

	mes: Try to avoid module name collisions.
	The old version of the Guile module system we use puts modules and
	variables in the same namespace.  This can cause collisions if you
	have two modules: "(a)" and "(a eval)".  When resolving "(a eval)",
	the module system looks up the name "eval" in the module "(a)",
	which is bound to the core "eval" procedure.  It then assumes it is
	a module and crashes.  This change sprinkles some "module?" guards
	around to avoid this problem.

	test: Move 17-compare-rotated to XFAIL in riscv64.
	* build-aux/check-mescc.sh: Add XFAIL block for riscv64 and add
	17-compare-rotated in it.

2023-10-18  Ekaitz Zarraga  <ekaitz@elenq.tech>

	test: 16-cast.c: Fix for riscv64.
	RISC-V64 has `unsigned char` for `char`, so it failed to build. In amd64
	`char` is `signed char`, so the code wasn't portable.  We have to be
	explicit about the sign of the `char`.

	* lib/test/scaffold/16-cast.c: Add `signed` to `char`.

2023-10-18  Ekaitz Zarraga  <ekaitz@elenq.tech>

	lib: Add setjmp/longjmp for riscv64.
	Note about the -tcc file:

	    HAVE_FLOAT_ASM defines if there's assembly support for float
	    instructions.

	    HAVE_FLOAT defines if there's floating point arithmetic support.

	    This is important for TinyCC because the assembler and the C
	    compiler are split. TinyCC can HAVE_FLOAT but no assembler support
	    for them.

	* lib/riscv64-mes-gcc/setjmp.c,
	lib/riscv64-mes-tcc/setjmp.c: New files.

2023-10-13  Ekaitz Zarraga  <ekaitz@elenq.tech>

	lib: int8_t set to `signed char` instead of `char`.
	`char` signedness is not defined by C standard.  In some architectures
	it's `unsigned` by default (RISC-V), so it's better to be explicit to
	avoid problems.

	* include/stdint.h (int8_t): Use `signed char` instead of `char`.

2023-10-11  Ekaitz Zarraga  <ekaitz@elenq.tech>

	lib: Define va_* for bootstrappable tcc in riscv.
	Bootstrappable TCC needs some extra definitions that upstream TCC
	obtains from `tccdefs.h` in its codebase, which is also injected in the
	binary using a weird trick (see `c2str` in tcc's codebase).

	* include/stdarg.h: Add definitions for variable length arguments.

2023-10-08  Ekaitz Zarraga  <ekaitz@elenq.tech>

2023-09-12  Ekaitz Zarraga  <ekaitz@elenq.tech>

	mescc: Fix switch statements' fallthrough.
	Flattens case structures as nyacc is giving consecutive cases as a
	nested block like:

	    (case testA
	      (case testB
	        (case testC BODY)))

	We convert to:

	    ((case testA (expr-stmt))
	     (case testB (expr-stmt))
	     (case testC BODY))

	And then treat them as independent cases. For the fallthrough we just
	add a jump to each case's body right before its clause (each of the case
	blocks is responsible of adding its own jump to its body):

	        // This doesn't have it because it's the first
	    CASE1:
	        testA
	    CASE1_BODY:

	        goto CASE2_BODY
	    CASE2:
	        testB
	    CASE2_BODY:

	        goto CASE3_BODY
	    CASE3:
	        testB
	    CASE3_BODY:

	This enables complex fallthrough schemes comparing to what was done
	before.

	* module/mescc/compile.scm (ast->info)[switch]{flatten-cases}: New
	variable.
	(ast->info)[switch]{statements}: Use flatten-cases on it.

	 * In the Guix bootstrap, we run module/mescc.scm directly
	       $MES -e '(mescc)' module/mescc.scm

	   places.

	Revert "nyacc: 0.86.0 compatibility stub. WIP"
	This reverts commit 0183cc1c42437fda27196e27b490285a61d47f59.

	While it works to run Nyacc 0.86.0, it breaks running Nyacc 0.93 and
	up.  This would need more thought and work, adding a nyacc-compat
	directory or so.  Seems not worth the effort right now.
