* Add a debug info when a #line directive is handled.seyko2015-03-031-0/+2
| | | | | The problem was: a debug info for the file which contain a #line directive (for example a preprocessed one) was wrong.
* Revert a grischka patch: gdb refused to know "main"seyko2015-03-031-1/+1
| | | | | | | | | | | | | | | It is a strange patch because before this commit a gdb is working well and after this commit there is exactly the same problem on Linux: gdb refuses to know "main" Author: grischka <grischka> Date: Tue Feb 5 21:18:29 2013 +0100 tccelf: fix debug section relocation With: tcc -g hello.c gdb a.out b main gdb refused to know "main" because of broken dwarf info.
* pp-many-files: don't drop a preprocessor defines when tcc going to ↵seyko2015-03-031-4/+0
| | | | | | | | | | | | | | preprocess a next file in the same pass like tcc -E one.c two.c three.c -o combined.i This will allow to speed up a compilation process by using a commamd like tcc -E *.c | tcc -o program.exe -xc - It looks that multi-times initialization don't affect anything. Only call to the free_defines(define_start) in tcc_preprocess() is removed in assumption that free_defines(NULL) in tcc_cleanup() will free all defines.
* A gcc preprocessor option -dD addedseyko2015-03-034-22/+84
| | | | | | | | | With this option on a defines are included into the output (inside comments). This will allow to debug a problems like: In file included from math.c:8: In file included from /usr/include/math.h:43: /usr/include/bits/nan.h:52: warning: NAN redefined
* Added a gcc preprocessor options -P, -P1seyko2015-03-034-10/+46
| | | | | | | | | | | tcc -E -P do not output a #line directive, a gcc compatible option tcc -E -P1 don't follow a gcc preprocessor style and do output a standard #line directive. In such case we don't lose a location info when we going to compile a resulting file wtith a compiler not understanding a gnu style line info.
* Move a line_ref variable from tcc_preprocess() function into struct ↵seyko2015-03-032-5/+6
| | | | | | | BufferedFile. This id needed for a right ouput in other places, precisely to calculate a number of empty lines which are waiting to output.
* A preprocessor should Interpret an input line "# NUM FILENAME" as "#line NUM ↵seyko2015-03-031-1/+6
| | | | | | | | | | | FILENAME" A cpp from gcc do this. A test case: tcc -E tccasm.c -o tccasm.i tcc -E tccasm.i -o tccasm.ii After a patch the line numbers in tccasm.ii are the same as in tccasm.i

* tccgen.c: Make sure that gen_op always returns an rvalue.Edmund Grimley Evans2015-02-231-0/+3
| | | | Either this fix, or an alternative one, is required for arm64.
* aarch64: Fix -run.Michael Matz2015-02-232-10/+54
| | | | | | | This adds some more support for properly transfering some offsets over the different stages of a relocations life. Still not at all psABI compliant and DSOs can't yet be generated. But it runs the testsuite in qemu-arm64.

* Fix handling of case_reg in switch statement.Edmund Grimley Evans2015-02-201-0/+3
| | | | | | The back end functions gen_op(comparison) and gtst() might allocate registers so case_reg should be left on the value stack while they are called and set again afterwards.

| | | | | | PS: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20101122/112576.html This is fix PR8686 for llvm: accepting a 'b' suffix at the end of all the setcc instructions.

| | | | Try "tcc -E -c tccasm.c -o tccasm.o"
* .i as file extensionseyko2015-01-061-1/+1
| | | | | | | | | | | Add a ".i" extension as alias for ".c" GCC and file extensions: .i C source code which should not be preprocessed. Before a patch: ./tcc -E tccasm.c -o tccasm.i ./tcc -c tccasm.i -o tccasm.o tccasm.i:1: error: unrecognized file type
* round() in test (24_math_library) fail because there are no defs included.seyko2015-01-051-0/+2

* Fix parsing of binary floating point numberLee Duhem2014-12-154-2/+133
| | | | | | | * tccpp.c (parse_number): `shift' should be 1 while parsing binary floating point number. * tests/tests2/70_floating_point_literals.c: New test cases for floating point number parsing.
* tcc.h (BufferedFile): Remove unnecessary static memory allocationLee Duhem2014-12-111-1/+1
| | | | | The memory needed by `buffer' will be allocated in `tcc_open_bf', these is no need to allocate them in BufferedFile statically.
* libtcc.c (put_extern_sym2): Extend the scope of buf to match its useLee Duhem2014-12-111-2/+1
| | | | | After leaving the code block that `buf' is defined, `buf' will not exist, so `name' will point to a variable that does not exist.

* Accept CPPFLAGS from the environmentMatteo Cypriani2014-09-071-1/+1
| | | | | | | Don't override CPPFLAGS so that it can be passed through the environment. (This is a patch Thomas Preud'homme wrote for Debian in February 2013.)
* tccelf: layout_sections: add missing param strsecMatteo Cypriani2014-09-071-3/+4

* Clear CFLAGS & LDFLAGS in testsMatteo Cypriani2014-09-072-0/+8
| | | | | | Clear CFLAGS and LDFLAGS to build the tests, in case the main Makefile passes some flags that aren't handled by tcc (we are not compiling tcc here, we are using tcc to compile the tests).
