herman ten brugge	5a370d8a6b	Relocation updates ... x86_64-link.c: Check relocations R_X86_64_32/R_X86_64_32S. These relocations can become to large if not configured with '--disable-static' or '--config-pie' and code is run with -run -ltcc. This only happens on x86_64. tccdbg.c: 1) Add some .debug (dummy) sections when dwarf is used. These sections are otherwise not relocated correctly for R_DATA_32DW. 2) Fix stab problem when reloc is applied twice.	2025-12-23 06:46:22 +01:00
herman ten brugge	64cf0b816b	undo x86_64-link.c commmit ... The relocation check does not work with stabs enabled on some targets. It works fine on fedora with and without stabs. So remove check.	2025-12-21 18:49:21 +01:00
herman ten brugge	96119149fe	Problems solved on for libtcc, pie, riscv64, arm64 ... I found some problems with a testcase from mailing list. On x86_64 an overflow on reloc R_X86_64_32 occurred that was not reported when using -run -ltcc. The problem could be solved by compiling tcc with -fPIE, -pie or --disable-static. Makefile, configure, libtcc.c, x86_64-link.c: - add --config-pie to configure help. Ignore -pie in libtcc.c and check reloc overflow in x86_64-link.c arm64-gen.c: - Fix reading from constant like '*(int *)0x7fffb7f1280c' elf.h, riscv64-link.c: - fix for -run -ltcc. Ignore reloc R_RISCV_SET_ULEB128 and R_RISCV_SUB_ULEB128 that are used in .debug_loclists section.	2025-12-21 07:05:55 +01:00

herman ten brugge	8569427459	Move -run -nostdlib code to lib directory ... tcc.h, arm-gen.c, arm64-gen.c, i386-gen.c, riscv64-gen.c, x86_64-gen.c: - remove old code tccrun.c: - update to use lib/run_nostdlib.c Makefile, lib/Makefile, lib/run_nostdlib.c: - new code tests/nostdlib_test.c: - testcode	2025-12-15 14:45:11 +01:00
Stefan	829c848520	tccpp.c: Configurable integer literal overflow handling ... Add the define TCC_CUT_ON_INTEGER_LITERAL_OVERFLOW to use the most significant digits of an integer literal before its parsing led to an overflow. When compiling tcc with another compiler, which is not able to handle 64 bit arithmetic, it is beneficial to use the last value before an integer literal overflows. Parsing 0x1000000000000000 then results in 0x10000000. The mescc from GNU Mes is able to compile a first tcc on a 32 bit system without 64 bit arithmetic. This change allows this first tcc to compile a second tcc with complete 64 bit arithmetic.	2025-12-13 18:53:15 +01:00

herman ten brugge	6da45946ae	Add bound check support for alloca on all targets ... stddef.h, tccdefs.h, tccgen.c, tests/boundtest.c, tests/tcctest.c: - remove ifdef arround alloca lib/Makefile: - move alloca-bt.o to COMMON_O lib/alloca-bt.S: - add alloca bound check code for arm, arm64, riscv64 lib/alloca.S: - check for leading underscore tcc.h, libtcc.c: - include arm64-asm.c instead of arm-asm.c for arm64 tcctok.h, tccasm.c: - add simple reloc support (only for R_AARCH64_CALL26)	2025-11-29 07:54:28 +01:00
Aleksi Hannula	fc424c9f7b	Reorder "pure" attribute ... Placing the definition of "pure" prior to TOK_DEFINE would cause it to be treated as a keyword by tccgen. This breaks building gcc, in which "pure" is used as a struct field name.	2025-11-28 16:07:24 +02:00
Aleksi Hannula	5b96aeb7fc	Implement some SSE/2 instructions ... This patch implements some instructions required by musl 1.1.24.	2025-11-28 15:23:09 +02:00

herman ten brugge	fa6a6bfbbd	Move lib/va_list.c into include/tccdefs.h ... This makes code with va_arg work with -nostdlib on x86_64.	2025-11-19 08:31:15 +01:00
herman ten brugge	3e8f1da9c5	Change asm into __asm__ in previous commit	2025-11-17 19:17:53 +01:00
herman ten brugge	c52b96cf85	Allow -nostdlib -run ... The -run option did not support -nostdlib correctly. The argc/argc/envp are now passed on stack according to sysv. This implementation does not work for TCC_TARGET_PE. Also arm64 does not work when running tcc compiled with itself. This is because arm64 assembly is not implemented yet. The following test code is used to check the code: #include <unistd.h> #include <sys/syscall.h> void _start() { syscall(SYS_write, 1, "hello world\n", 12); syscall(SYS_exit, 0); } Run this with: ./tcc -nostdlib -lc -run a.c make tcc_c ./tcc_c -nostdlib -lc -run a.c	2025-11-17 14:00:15 +01:00
DFP	d9ec17d334	Relaxed the 'incompatible pointer type' warning a bit ... Do not emit that warning when the source struct (recursively) contains destination struct as the first member. For example, in this case the warning would have been emitted before, and is not anymore: struct base { int a; }; struct derived { struct base base; int b; }; struct derived derived; struct base *base = &derived; I personally use that pattern in my code (in a bit more elaborate form) and so this change removes the warnings for those use cases, while still retaining it for everything else. Feel free to CC me on the mailing list if you have questions, suggestions or complaints.	2025-11-14 08:55:55 +01:00
herman ten brugge	ab2ce3b13a	Ignore some more attributes ... Detected when using -Wunsupported	2025-11-04 15:03:19 +01:00
Detlef Riekenberg	cdebce3079	tccpp: Add the define __STDC_HOSTED__ [C99] ... Usually defined to 1, but when using "-nostdlib", the value is 0 (required for C99) -- Regards ... Detlef	2025-11-01 18:11:49 +01:00
Avi Halachmi (:avih)	f4e01bfcab	tcc -run: support custom stdin with -rstdin FILE ... When tcc -run is used with input file from stdin, then run_main's stdin (which is tcc's stdin) is already EOF after we've read it. If the program operates exclusively on stdin, then it cannot be used. This commit adds an option -rstdin FILE which sets run_main's stdin. Can also be used in such case to set run_main's stdin to the tty, using -rstdin /dev/tty (posix) or -rstdin con (windows).	2025-10-27 14:50:56 +02:00
Avi Halachmi (:avih)	234e2dd2bf	tcc options: document behavior and clashes (no-op) ... The tcc options behavior is non trivial, and it's also susceptible to ambiguities - which do exist (but currently are not painful). - Add a script 'optclash' which detects clashes/ambiguities. - Document the parsing behaviour and current clashes/resolutions as comments in libtcc.c .	2025-10-27 14:50:54 +02:00
Aleksi Hannula	01d1b7bc76	Add support for f{l,s}d in riscv64-gen	2025-10-17 15:40:08 +03:00
herman ten brugge	19589288cb	Some fixes and cleanups ... tcc.h, tccgen.c: Add and use IS_BT_ARRAY tccpp.c: free memory when size is 0 in realloc code tccdbg.c: move common code to seperate function remove_type_info	2025-10-16 07:35:27 +02:00
herman ten brugge	edcd228214	Init global_expr variable ... This is needed when errors occur when compiling with libtcc. A next compile with libtcc results in undefined symbol.	2025-10-15 10:02:09 +02:00
herman ten brugge	96229004c4	Fix debugging after commit tccgen: more of scope hacks ... The commit added some extra defines that where not handled in debugging code.	2025-10-15 09:01:54 +02:00

grischka	34b45a69ff	Reverts & cleanups ... - include/stddef.h, tcctest.c Revert "tests/tcctest.c: include stdint.h" This reverts commit 8f23997ca7 We don't want tcctest.c to rely on system include files - libtcc.c: Revert "libtcc.c: Remove unused defines free and realloc" To be unused is the point why they do exist This reverts commit 2f88764100. - tcc.c: fix formatting of commit e73529865d - tccpp.c: parse_include(): print skipped include files too (with tcc -vv[v] file) next_nomacro(): faster L"str" parsing - tccgen.c: fix c2y if declaration: * accept like GCC: if (int a = 0, b, c = x; c) * accept as "TCC extension": if (int a = 0, b, c = x) * "speak tcc" with symbol/function names - README: cleanup	2025-10-09 13:08:33 +02:00
herman ten brugge	ce8b3432bf	Allow gcc 16 for build	2025-10-07 14:32:13 +02:00
Stefan	bcfb872fd0	Makefile: Add space behind 'install -m' ... There are install shell scripts around, often derived from X11 like contained in glibc or Gash sources, which require to separate -m from its value. Therefore add a space behind 'install -m' in the Makefile.	2025-10-03 17:58:45 +02:00
Stefan	ba0899d909	tccasm.c: Make .init and .fini sections executable ... GAS selects default attributes for a section based on its name and makes the sections .text, .init, .fini executable. The crti.s and crtn.s files of musl rely on these defaults and don't set the "x" flag for the .init and .fini sections. Unfortunately TCC does not care for .init and .fini section defaults in assembler or C code. Fix this for assembler code.	2025-09-21 14:06:59 +02:00
Stefan	2f88764100	libtcc.c: Remove unused defines free and realloc ... These defines are not used in the code below their definition. They are defined in tcc.h as well.	2025-09-21 13:30:15 +02:00
Stefan	95d184cba1	i386-asm.c: Optional % for variables in specific registers ... Handle 'register long r10 __asm__("%r10")' without %, too. Using GCC the % is optional. The musl source code does not use the % prefix. The GCC source code uses both variants.	2025-09-21 13:18:37 +02:00
Stefan	5aebf106e8	i386-asm.c: Use NB_ASM_REGS instead of 8 ... For x86_64 there are more than just 8 registers.	2025-09-21 12:21:27 +02:00
Stefan	9dc59f9c23	i386-asm.c: Do bit-check for OP_SEG in asm_opcode ... Fix a bug with "call *%%gs:16", which sets the two flags OP_INDIR and OP_SEG in pop->type.	2025-09-21 12:18:11 +02:00
grischka	de8c19e1da	tccgen: globalize function return type too ... Commit 38ab5f65b3 was missing to move the function return type to the global stack too. Also, check redefinition in sym_push(), as before.	2025-09-18 19:32:19 +02:00
noneofyourbusiness	47106ce103	tccgen.c: silence logical op warning ... behavior is unchanged	2025-09-18 11:42:58 +02:00
noneofyourbusiness	8f23997ca7	tests/tcctest.c: include stdint.h ... despite being defined in tcc's own stddef.h, intended to be included by libtcc.h, libtcc.h actually included the libc's standard include tested on musl	2025-09-18 11:17:55 +02:00
noneofyourbusiness	e73529865d	tcc.c: add information about reporting bugs to the mailing list	2025-09-18 09:58:21 +02:00
grischka	38ab5f65b3	tccgen: more of scope hacks ... * case 1: local scope of 'ff' int main() { int ff = 123; { int ff(int): ff(456) }} * case 2: linkage of a static extern symbol (older gcc did allow that) static int ff(int); int main() { int ff(int): ff(456) } Also: - cleanup enum, let sym_push() handle redefinition - just mark incomplete array base types, unshare only when needed (in decl_initializer_alloc()) - fix sizeof empty array (= 0) : int ii[] = {}; - rename 'Sym' members used by __attribute__((cleanup(f)))	2025-09-08 17:23:18 +02:00
