From 224236f57c7d645c9b23d717de354df5d12b98b6 Mon Sep 17 00:00:00 2001 From: Vlad Vissoultchev Date: Sun, 17 Apr 2016 16:37:23 +0300 Subject: Improve hash performance - better `TOK_HASH_FUNC` - increases `hash_ident` initial size to 16k (from 8k) - `cstr_cat` uses single `realloc` + `memcpy` - `cstr_cat` can append terminating zero - `tok_str_realloc` initial size to 16 (from 8) - `parse_define` uses static `tokstr_buf` - `next` uses static `tokstr_buf` - fixes two latent bugs (wrong deallocations in libtcc.c:482 and tccpp.c:2987) --- tcc.h | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'tcc.h') diff --git a/tcc.h b/tcc.h index 208af44..6fc3775 100644 --- a/tcc.h +++ b/tcc.h @@ -365,9 +365,10 @@ static inline void write64le(unsigned char *p, uint64_t x) #define IFDEF_STACK_SIZE 64 #define VSTACK_SIZE 256 #define STRING_MAX_SIZE 1024 +#define TOKSTR_MAX_SIZE 256 #define PACK_STACK_SIZE 8 -#define TOK_HASH_SIZE 8192 /* must be a power of two */ +#define TOK_HASH_SIZE 16384 /* must be a power of two */ #define TOK_ALLOC_INCR 512 /* must be a power of two */ #define TOK_MAX_SIZE 4 /* token max size in int unit when stored in string */ @@ -1161,7 +1162,7 @@ PUB_FUNC void tcc_warning(const char *fmt, ...); ST_FUNC void dynarray_add(void ***ptab, int *nb_ptr, void *data); ST_FUNC void dynarray_reset(void *pp, int *n); ST_FUNC void cstr_ccat(CString *cstr, int ch); -ST_FUNC void cstr_cat(CString *cstr, const char *str); +ST_FUNC void cstr_cat(CString *cstr, const char *str, int len); ST_FUNC void cstr_wccat(CString *cstr, int ch); ST_FUNC void cstr_new(CString *cstr); ST_FUNC void cstr_free(CString *cstr); @@ -1246,7 +1247,7 @@ ST_INLN void tok_str_new(TokenString *s); ST_FUNC void tok_str_free(int *str); ST_FUNC void tok_str_add(TokenString *s, int t); ST_FUNC void tok_str_add_tok(TokenString *s); -ST_INLN void define_push(int v, int macro_type, int *str, Sym *first_arg); +ST_INLN void define_push(int v, int macro_type, TokenString *str, Sym *first_arg); ST_FUNC void define_undef(Sym *s); ST_INLN Sym *define_find(int v); ST_FUNC void free_defines(Sym *b); -- cgit v1.3.1
